6 -Hint: height of the small bucket is 15        ( I already calculated it properly, don't double check)
The question is:
b) given that the small bucket has a volume of 850 cm^3, find the volume of the large bucket
I tried solving it, and I got the final answer 6816 cm^3, is that right or not? thx in advance

The deminsions are 2 times the smaller bucket.

Volume is 3 deminsions, so 850 * 2 * 2.

Oops, I forgot to multiply a 2.

850 * 2 * 2 * 2

small bucket

pi r^2 h = 850 cm^3

now make dimensions larger

pi ( 2r)^2 2h  = ?

(8)  pi r^2 h  = larger bucket

(8) (850) = 6800 cm3

why did you assume it's a cylinder?
now im confused cuz we 3 got different answers.

I think you will have to be given more information if you assume it is a conic section or other....

but volume is basically a   3 dimensional  construct    l x w x h     or     area x h

you increased the base area x4     and you increased the height by a factor of two

4 x 2 =   8 times the original volume        (without assuming a cylinder)

We  have similar  3D figures

The scale factor of the large  bucket to  the smaller =  2

Volume of larger bucket  =

Volume of smaller bucket  *  (scale factor  )^ 3  =

850  (2)^3   =

6800  cm^3     (as EP found)   Jun 4, 2021
