- 👉 Learn how to find the area and perimeter of a parallelogram. A parallelogram is a quadrilateral with two pairs of parallel sides. The area of a shape is the measure of the portion enclosed by the shape while the perimeter of a shape is the measure of the outline enclosing the shape.
The area of a parallelogram is given by the product of the base and the perpendicular height while the perimeter of a parallelogram is given by the sum of the lengths of the four sides of the parallelogram.

To simplify it for you all get your area and divide it by pie, once you've done that, get that answer and square root it, then you should get your answer 🤓
Z A R A u are a genius
Thank you I get mixed up with symbols 😂
How old are you not trying to be weird or anything 😂
BearsGoMoo calm down it was probably a small mistake at least they still said everything else right
Thank youuuuuu
literally taught me better than my real teacher lol
EXACTLY!!!!!!
Math teachers: You cant use calculators!
Also math teacher: *uses calculator*
You can't use calculators for easy equations but when it gets to bigger numbers that are more complicated then you can use a calculator
I swear bro its so annoying.
You can’t do Pi without a calculator
Legend has it, there is no one in his class room
ya
like my mortal existence, empty, in brain
for the last part, he divides 201.1 and π first,
then takes the whole answer and square roots it,,.
here is the whole schtick:
take the original formula first:
--> A=πr²
substitute the given AREA, which is 201.1 square inches, so:
--> 201.1 = πr²
since we are finding RADIUS, we divide each side by π, so that only RADIUS will be left on one side:
--> 201.1/π = πr²/π
we cancel the two π's on the right side, so only RADIUS SQUARED (r²) is left on the right side:
--> 201.1/π = r² (i will flip the equation)
now, you have to get rid of the ² next to the r, so you SQUARE ROOT both sides of the equation:
--> √r² = √201.1/π
the ² next to the r is cancelled out, then divide what's inside the square root first:
--> r = √[201.1/π]
the WHOLE answer you have to square root:
--> r = √64.0121181116
and here is the final answer, hope it was clear!:
--> r = 8.00075734613 or 8.0 inches
Me no understand
same

my guy you are an incredible teacher, thank you so much for making these lessons
Very good teacher. Straight to the point
I wish you were my teacher this was so simple and quick the teacher I have rn spent 1 hour trying to explain why it worked and it just confused everyone
thanks, it helps so much.
no no it doesnt
It helped me too on test

its kinda funny hes working on the same problem as me

STOP BRINGING TIKTOK COMMENTS ONTO YT. THERE ARE NO POVS ON CZcams. PLEASE SHUT UP :)
McLogan really came in clutch for the finals 😅
I was finding it hard as a 13yo but niw I get it thx
Thanks very much. Explained very good .
You are very welcome!!
thanks now I can destroy my paper
Only vids that actually have helped
Thanks mate
Thanks Teach.
Thank you so much. You work wonders 🙏🏾
thank you!
not bad
Hello, this video helps so much with the chapter I’m on, I’m really grateful🥲
Thank you
thank you so much
if you're watching this ms ho pham probably made you
oh my god had had no idea where to even start with this and i immediately got it after this thank you so much
Thank You Sir!
Thank you man you saved me!!!
what grade does he teach?
5 i think so
Thanks man
Brilliant
I never cheated, but he passed the test as a math teacher in his career cheating. His name properly already on the hit list.
how do you find the square root again?
there is supposed to be a √ symbol on your calculator
you put the symbol behind the number that you are trying to square root

@@nthwielder thnx u simplify the teaching so well even in text
@@nthwielder can u tell me how did u divide the third last line
@@olkkkk7ui513 ohhh i can't, sorry 😅😅 I wrote this a long time ago and i forgor the whole thing!! good luck thooo and thank u!!
@@nthwielder it's ok thnks for replying
How about the other way around..... I have been searching the net for itbut mo one has made it as yet...for example i have the radius but meed to find the area...ok lets say my radius is 21 cm and to find the area i wrote this ,A=π2 π= 3.14 andam stuck there😅
do you mean you don't know how to find the area of the circle?? because if so it's just radius squared (radius x radius) and then multiply by pi
this mans waffling just do pie divided by your answer then square root it
yep
Whats the equivalent of pie?
or 3.14159 if you're spicy

nice
