What's this
@@intoworld71 the last question of the higher maths edexcel paper we had this morning, it was đ
How many marks (if any) would I have gotten cos what I did was find the area for the whole of the shaded circle and got 16 pi and then I split one of those sectors/segments (a-b) as though it were a semi circle and got a total area of that section 4 pi and then doubled it as there is 2 of them and got 8 pi and then I did 16 pi - 8 pi to get 8 pi (which is obviously wrong) as my final answer
Thankyou for assuring me that i got the wrong answer.
Yes i had it on my gcse couldn't solve it in the exam but did it in about 5 min after the exam had to explain it to my head of maths was a good question
The way I answeeot was different I saw it as 4 identical segments in between the intersections of the circles if that doesn't make sense the circle be where its not shaded you can cut in half and get a segment there are four of them I then worked out the area of the sector using the equalatral triangles and then took the area of the triangle in the sector to leave the segment I then multiplied this by four as there are four segments and took this off 16 pi
I can't remember my answer tho as I put the paper in the bin after and haven't looked back since
My uncle has a degree in maths and physics. I showed this question to him and it took him a good 20 minutes to solve it, he said that's one of the most challenging gcse questions he's seen in a long time.

How was your paper today maths
Where did you find it ?
is that true??
Bruh how
Not true
I found it much easier to simply work out the small lens-shaped bits by subtracting the hexagon from the circle dividing by six and then subtracting four of these lenses from one-third of the area of the circle. Just use Pythagoras for the triangles. Doesn't need any trigonometry at all. Hope this helps, shows that it is good to look for shapes in these questions.

Bruh fr this question is why they said good luck on the advice part đ
I know haha. I was so shocked and almost happy when I saw that and then seen this question and was like ahh thatâs why.
This question was great; I managed to do it in about 10 minutes because of a method I have for geometry questions. Advice people: If you ever can see a method for a geometry question within 2-3 minutes, just draw lines. Where ever you want. Just draw them. It will really help, trust me. - Anonymous Internet Person. Thanks GCSE Maths Tutor for finding this question on the latest GCSE paper :D
yhh thats what I did too but in the end, I got 8 pie which is obviously wrong.
wdym 'just draw lines' đ
i got the answer to be 64-16Ï... if you draw a square over the middle circle...!Which will be tangent to three of the circles..and join tge diameter of two of the circles vertically! and a line drawn from tge centre of the circle to the tangent is perpendicular...so the figure was a square..and since diameter was 4+4 cm = 8cm....so the square was of area 64cm^2.. and then inside that we got two identical semi circles...i have subtracted the area of semi circle from the square and then got the shaded regionn...There are many ways to solve a question!
POV: You memorise the exact trig values and don't even get to use them.
Couldn't be me.
I got the same answer with a different method. I split the the two intersecting shapes into two identical segments, then found the area of one of those segments and multiplied by 4. This was a very fun and challenging question, and one of the hardest GCSE questions I've seen.
No marks for u
Why not? Itâs a valid approach to the question
@@ryankelly4830 it says on the mark scheme BJ made that it has to be this method

This was indeed a challenging question and i did it by subtracting 4 equal segments from one circle and convinced it is a lot quicker, although i do like your approach. Itâs always nice and refreshing to see a different approach. Thank you.
I did the same
How would you subtract 4 equal segments?
Thatâs a brilliant idea! Did you get the right answer?
Thanks to your videos and the way u explain these type of difficult question I think I was able to to grab at least one or two marks for this questions as I too also drew a triangle attempting to find out the segment,but ran out of time as most the time I was just stuck! Also wanted to tanks u for ur videos which made most of this paper a breeze.
I find it beneficial for questions like this to break it down into a 'shape equation'.
Half of shaded area (split vertically) = semicircle - lens.
Half of lens = sector + (sector - equilateral triangle) = 2 x sector - equilateral triangle.
Areas of sectors (60°, r = 4), equilateral triangles (side = 4) and semicircles (r = 4) are all pretty straightforward to calculate.
Looks like the whole country did badly here (and also with some of the other ones at the end of the paper), so maybe the exam board will make an exception?
LEts hope so~
wdym make an exception ? btw stuff like this is put in every year to identify prodigies nobody ever gets these marks
hope so
@@Georgeg15 not in a year when after 2 yrs of lockdown and chaos we have exams. And not in a yr when they said it'll be easier but then hit us with a question I haven't even since in past papers PRE PANDEMIC
@@Georgeg15 I did all the past papers and by far this shit was the hardest question ever, they expect too much from a 16 year old
I got this right in the exam
The way I did it was at 2:09 the area of that half oval section is two overlapping circle sectors with an equilateral Trinangle ( and each circle sector had 60 degree angles cuz of the equilateral)
So find the area then multiply by 4 and subtract that from 16(pi)

This question is so much easier when you know what a radian is. But that is from a year 1 A-level perspective
or additional mathematics student
Then why tf is Edexcel slapping us questions beyond Seconday school education. The GCSE -> General Certificate of Secondary school is only meant to measure secondary education. :(
@@H8ssan Because it is possible to do at GCSE level as you learn about areas of sectors in circles. It just becomes easier in A level when you learn what a radian is

Does anyone think that writing 1 circle = 16 pi is worth a markđ I doubt it
Lol, I did the same thing
Yes it probs is worth a mark
it should be as working that out is necessary to figuring out the complete answer (props only 1 mark tho)
same here lol
I wrote that as well. I doubt it too. Perhaps if we'd written the formula down for the area of a sector of a circle we might have got a mark?
I didnât do this test but I got it slightly differently. If you split the shape into the equilateral triangles, instead of working out the sector, I just worked out that 3*(area of one triangle) + 3*(outer semi-circle looking shapes) = 8pi, and then I worked out the area of one small semi-circle thing by dividing this by 3, and then the area of the shaded region is 2(area of equilateral triangle - area of one semi-circle thing). Rip to ppl who got this question but extra rip to further maths students
Hi, thanks for this great video explaining how you solved it. I attempted it (but failed miserably) before watching your video about a month ago. I tried to solve it again today after 2 cups of strong coffee and managed to get the correct answer....after 30 minutes, which is way too long to spend on just one question. The solution, broadly speaking is "Area of two segments minus area of four sectors." The sectors in question are the fractional area (60/360th) of full circle minus the area of the equilateral triangle formed by AB (or BC) and the circle intersects.
You get a lot questions like this in the UKMT
I loves this question ^v^
fianlly a well explained video on this heack of a question!
Area of an equilateral triangle can easily be calculated by dividing into two right angled triangles and using pythagoras - no need to remember any trigonometry.
I am in second year at uni and it still took me about 10-15 mins or so answering this question. Got the answer right in the end, but definitely a question that targets the grade 8 and 9 students.
I got till 16 pi then i did not know that we have to draw the triangle and use cosine rule, I feel they dashed this down from A level To GCSE
It's more of an old-fashioned problem from something like Durell's book "New Geometry for Schools" (published in 1956) that was used extensively in secondary schools into the early 1980s for the O-level. More recently, they turn up as Math Olympiad questions from time to time. It used only GCSE techniques (construction of equilateral triangle, area of sector and segment, sin 60° = â3 / 2) but presented in an unfamiliar form as a challenge for grade 9 students.
i had this exact question in a mock on monday, just wish iâd seen this earlier đ©
I got a 9 in GCSE Maths and an A* in A Level Maths and Further Maths. Almost shamefully, this question took me 20 minutes to work out. If you couldnât work this out in the exam, please donât beat yourself up about it!

Great video sir good job hard question.
Glad you liked it!
Damn this took me a whole lot more steps than it took him. I didn't clock that the 3 segments mentioned are all equal. I did a different method I correctly reacehd the same solution. Goes to say that there are many routes to the right answer.
I'm an A Level student who solved this problem in like 5 minutes, but even then, this is by no means an easy problem.
I bet you that 80% of my further math class dont know how to solve it.
I really have 0 idea how edexcel could have put a question like this.
Go on lad
I wanted to cry in that usually get grade 9 and managed to zoom through paper and then spent half an hour slamming my head against the table in this question đđ
I used pythagorus on the equilateral triangle to get the area. Then took that away from a sixth of the circle area to get the segment bit, then to that away from the triangle. A bit quicker than the above.
Can u even use Pythagoras on an eq triangle
@@estherereyemi9309 If you split the equilateral triangle in half, you have 2 right-angled triangles. You know the hypotenuse (in this case 4cm), and you know the short leg (2cm), so you can use Pythagoras to calculate the long leg, and thus you have the height of the equilateral triangle. You already know the base, so just use the standard formula to calculate the area.
It's basically the way that the formula for the area of an equilateral triangle [ = (â3/4)aÂČ ] is derived.
@@Grizzly01 wait that's so smart
I sat the IGCSE and saw this on reddit after, took less than 2 mins to figure out.
I'm actually a predicted 6 student but had the exact same methodology in my head, if only I trusted my gut I could've surprised my whole year 10 group XD
Hope this question have lowered the grade boundaries đąđ cause I got my GCSE next year and Iâm scared
grade boundaries are different each year and it doesn't matter from previous years. they are created after all the papers are marked each year to tailor it to the year 11 that did the exams that year. Hope this helps
Your grade boundaries will depend on how YOU and your year 11âs in the country do next year
Iâm fully convinced this is the hardest gcse maths question Iâve ever seen (not including further maths)
So my way of getting the 5 marks was actually way easier, I first worked out the area of the 3 circles added them together then skipped the rest of the question to get back the 5 marks through not wasting my time on this dumb question and doing an easier question instead
Bro this question, the vector one and the ratio one fucking killed me
I spent over 10 minutes on the ratios one and still couldn't solve it!!! The vector one was easier tho, you had to show they are multiples of ach other :)
pretty sure most people didn't get this
Edexcel maths is crazy. so glad we do OCR
I've finished solving this with the correct answer. However, it took me around half an hour. I had a blast while solving it :)
only the smartest of the smart got this becuz this was acc mad
Could you make 2 triangles with base AB and BC
Then work out those tiny segments
Add them together
Then work out the area of a semi circle
Then subtract the area of the semi circle from that?
mabye
Do you have ocr specific videos for paper 5 ( second higher tier paper which is non calc)
Im pretty sure this question was inspired by the olympic rings. Nevertheless, thanks, this will really help me when I do my GCSEs next year.
This solution is WAY over-complex, simply it is the area of a parellelogram minus area of sector (1//6 of a circle) this gives 1/2 . r . sqr(12) - pi.r^2 / 6 then double it !
ooops! ... that should be ..... r.sqr(12) - pi . r^2 / 6 then double it (where r=4 and Sqr(12) is height of //ogram using pythagorus on the equilateral triangle))
Using a parallelogram you would have to subtract the area of a sector and a segment before doubling it, which is the same method I used except you also have to incorporate Pythagoras to find the area of a parallelogram rather than the area of a triangle.
A really nice method but I wouldnât say itâs easier, nor would I say itâs more or less complex! But definitely another interesting way of looking at it that I had considered!
All in all I used 5 different methods - this one included! And the method presented here was the preferred method by my students đ
Of course we are all different and I would always encourage using the method that you prefer!
Thanks for sharing this one!
@@TheGCSEMathsTutor Tut tut tut ... look again , not so ... the equivalent of the exterior segement is incorporated in the //ogram so it is simply area of //ogram minus area of sector ... then double it ... elegant !
The first time i tried this problem, i thought using the area of an elipse might do the trick, but then i realised that it's not really an elipse

Just had this question in my paper 1 for my GCSE, took me 20 minutes of checking to make sure there were no mistakes. Shame to learn that this question was leaked so who knows whether ill get the marks for it but it was fun walking out of the exam hall learning I was the only person who even answered it. Sadly that 20 mins spent meant that i couldn't check my paper for stupid mistakes and i learned that i have made like simple addition mistakes in the 3 other final questions soooooooooooooooo rip me.
Edit: info about bad additions
Well done for completing it. Several of our students did too, but we enter a cadre into the Math Olympiad to give them a wider experience of questions than those in the text book.
Don't worry about the marks, that's up to the exam board to sort out. Given the surprise over the question, my thinking is that the leak was not widespread and the board will look for clusters of anomalous correct answers above an ability indicated in the rest of the papers; if that's the case, most students will gain marks for answering it.
this is ligitemtly child labour
yo so many ppl hated that question at sklđđ
I did most of this but i forgot how to work out a sector so i just named it X and wrote my answer in terms of X
I just had this question in my GCSE mock paper
If it took him more than 6ms how does edexcel expect us to do it in 5minutes lol
My first impulse was to use polar integration. Then I realised this question is for 16 year olds.
The key to this question is knowing that the circles intersect like hexagons, without that your stumped. I think itâs unfair to expect any gcse students to know this and apply it in an exam in such an obscure way
It is only simple geometry - the area of a circle and the area of a triangle, nothing too challenging there!
@@karhukivi the method and working out was light work, but ACTUALLY noticing the triangle at the very beginning under EXAM PRESSURE is nearly impossible

Damn thats tough. Glad that didn't come up in the paper đČ
Honestly I got to the second last step and panicked when I saw 64/3pi - 84/3pi thinking it was negative but forgot to add 16root3, genuinely thought it wasnât too hard and *relatively* easy. (I still remember the answer I put was a little bit wrong but I know for a fact I at least going to get the 4 method marks)
How did you get 64 and 84?
i just did my math exam last week and this question came up i wished that i had seen this video before .
thank god I was doing the ocr exam
My maths teacher showed me how to do this, I usually have like 40 mins by the time I finish the paper but I doubt I would've worked it out myself in that time.
Yes itâs a tricky one under time pressure for sure!
It honesty wasnt that bad, but i left my answer as 8 root 3 minus pi 4.6 reoccuring, would i get full marks for the question?
