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

Not all heroes wear capes, THANK YOU COGNITO FOR EVERY VIDEO YOU'VE UPLOADED!!

I do not know about frustum more like frustrating...

[@ateefrehan6133]

Thank you sooo much for this video 📈📈📈

Ty cognito watching this a day before my GCSE maths exam

[@ireoluwaemmanuel948]

How did it go

[@nsemizap9084]

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.

[@patrickadi6155]

I have my test.. TODAY... Thank you so much!

[@tahakhuwaja5917]

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?

[@pratikshyajalli3806]

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

[@sumdumbmick]

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.

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 !

[@Ruhal567]

Thanks for such a cool topic about a cool shape

[@kevinfrench524]

Very clear instructions. Thanks so much for the helpful video!

[@NonhleLydia]

This helped so much thank you❤

[@yourlocalpostman]

Could you make a video on vectors, if possible?

[@Kingdavid_3]

I think there is one

[@Kingdavid_3]

If u mean physics

[@yourlocalpostman]

@@Kingdavid_3 nah I was referring to the grade 8/9 vector topic in maths, vectors in physics is easy lol

[@Kingdavid_3]

@@yourlocalpostman oh ok I'm also in grade 9 but I don't know vectors in maths 😂

[@Kingdavid_3]

So it must be important

[@zehongzhou5675]

do we need to memorise the volume of a cone for edexcel gases pls respond my exam is tmrw

[@adam7657]

Yes we do, area of base x height x 1/3

[@OgundejiOredolapo]

Tomorrow is exam and I have to watch this . thank you

Thanks man I appreciate it

[@bigmanyondos]

how did you get 20 please help me on the small cone

[@newtopazhawk9930]

How do you find out the height if a frustum

[@zehongzhou5675]

got stuck on these questions for so long b4

[@OmololaAyanshola]

Thanks

[@sugaaa4721]

Thank you

[@nileytara2280]

❤ Ur vids could u upload a vid on transformation pls😊

[@Flash_editzzz]

What if i dont have the hight of frustrum

[@aspectclaw6411]

May I ask you to make videos about space and GCSE or make a how to revise videos

[@Cognitoedu]

Hey, we already have a few space ones in the physics playlist - hopefully they have some of what you’re after!

[@aspectclaw6411]

@@Cognitoedu yes I have seen them can you make videos on propulsion systems or faster that light travel

Volume of Frustum of a Square to Cone?

[@Venom-nk8nd]

Thanks 🇵🇬🇵🇬,,

[@ersan1798]

So,where can I get ppt?

[@Mogw]

Bruh what if there is no 50cm

[@xnetion2239]

i have that problem they didnt give me the full height only the height of the large frustum cone

thanks!!!
