Answer 2

Why are you finding the volume if you already have the volume-?

Answer 3

oops I meant the height

Answer 4

Oh, kay, so \[ V = pi(r^2) (h) \]
like base time height

Answer 5

So fill it in
\[785 = \pi(5^2)(h)\]

Answer 6

then find h

Answer 7

Yea, I already know the formula. Im just confused on how to find the height.

Answer 8

Well simplify that ^^^^
we have
785 = 25pi(h)
so do 785 divided by 25pi

Answer 9

10?

Answer 10

yea if you round

Answer 11

So is that what the height would be?

Answer 12

Yes, approximately

Answer 13

Put if you want an exact answer, maybe leave it in the 785/25pi form
if you want rounded answer, yea 10

Answer 14

Ok, Thank you!
