given the linear ratio between the diameters, a : b the fundamental frustum constant, m, is given by: name the variables such that a > b c = a^3; d = b^3 m = (c - d) /3 pi/4 *m /c = vol of frustum relative to rectangular prism containing the full cone (multiply this by 4 *R *H) pi/4 *m /d = vol of frustum relative to rectangular prism containing small cone (multiply this by 4 *r *h) believe it or not, this is less work than the way you did it, and it generalizes to all frusta. just replace the fundamental circle constant, pi/4, with the shape constant for whatever the base is.
Saw a video calculating rates of reaction on your channel. How can I use the rate of reaction to calculate the rate constant for a first-order reaction using the volume of gas collected?
Hey dear, I think I have a perfect guide book for your practice and am sure that will help you a lot. If you are interested to get some improvement in you I can provide you that guide. All the best
OMGGGG THANK YOU SO MUCH ! I FINALLY UNDERSTAND !! MY TEACHER WHO IS APPARNTLY THE BEST MATHS TEACHER COULDNT EXPLAIN IT WELL , BUT COGNITO EXPLAINED IT WELL ALL UNDER 4 MINTUES ! THANK YOU SO MUCH I LOVE YOUUU GUYS !

Not all heroes wear capes, THANK YOU COGNITO FOR EVERY VIDEO YOU'VE UPLOADED!!
I do not know about frustum more like frustrating...
I never got this thing and lost loadsof marks in my mock for it. you've just made it so simple, you guys are legends ty
Ty cognito watching this a day before my GCSE maths exam
How did it go
Thank you sooo much for this video 📈📈📈

Thank you so much! You explained it so quickly and easily to remember I am sure if we were taught it in class it would take up the whole lesson.
do we need to memorise the volume of a cone for edexcel gases pls respond my exam is tmrw
Yes we do, area of base x height x 1/3
Could you make a video on vectors, if possible?
I think there is one
If u mean physics
@@Kingdavid_3 nah I was referring to the grade 8/9 vector topic in maths, vectors in physics is easy lol
@@yourlocalpostman oh ok I'm also in grade 9 but I don't know vectors in maths 😂
So it must be important
Tomorrow is exam and I have to watch this . thank you
This helped so much thank you❤
Very clear instructions. Thanks so much for the helpful video!
helped a lot
fr
very helpful explanation thank you so much
Thanks
Thanks 🇵🇬🇵🇬,,
What if i dont have the hight of frustrum
OMGGGG THANK YOU SO MUCH ! I FINALLY UNDERSTAND !! MY TEACHER WHO IS APPARNTLY THE BEST MATHS TEACHER COULDNT EXPLAIN IT WELL , BUT COGNITO EXPLAINED IT WELL ALL UNDER 4 MINTUES ! THANK YOU SO MUCH I LOVE YOUUU GUYS !
How do you find out the height if a frustum
Thanks man I appreciate it
Volume of Frustum of a Square to Cone?
Thank you
got stuck on these questions for so long b4
May I ask you to make videos about space and GCSE or make a how to revise videos
Hey, we already have a few space ones in the physics playlist - hopefully they have some of what you’re after!
@@Cognitoedu yes I have seen them can you make videos on propulsion systems or faster that light travel
So,where can I get ppt?
thanks!!!
Bruh what if there is no 50cm
I love cheap whiskey
?
