Help on 9th grade algebra problem?!

[From: ] [author: ] [Date: 13-01-23] [Hit: ]
......
please help me with the question I don't understand it:
A cylindrical can has a volume of 5625 (pie symbol) cubic centimeters. It's height is 25 centimeters. What is the radius of the can? Use the formula V= (pie)r2h
please and thank you!! :)

-
V = pi r^2 h
if V = 5625 pi
then r^2*h = 5625
and if h = 25
means r^2 = 2625/h = 5625/25 = 225
and so r = squareroot of 225 = 15
