thats correct !

ganeshie8 · Answer

you just compute the volumes for both. and take ratio

Thanks. I just wasnt sure if you had to square root it or not

ganeshie8 · Answer

hmm what  ?

zeesbrat3 · Answer

Well 64 can be square rooted, and I know that with certain problems, you have to. Unless Im probably thinking to hard on this problem and I got myself all confused, which is likely.

ganeshie8 · Answer

you thinking too hard. and you shouldnt square root 64, becos :

ganeshie8 · Answer

question is asking how many times the volume of Y  is bigger than volume of X

ganeshie8 · Answer

Volume of Y = $\pi. r^2. h = \pi . 60^2 . 40$
Volume of Y = $\pi. r^2. h = \pi . 15^2 . 10$

you take Y/X 

it gives how many times Y is bigger than X

Okay, I guess I got used to harder problems. Thanks. :)
