Hi Morgan,

Volume is usually equal to base area times height.

if you have a cylinder and its volume is 500cm^3, then we can write

500 = 10*A where A is the base area of the cylinder.

A = 50 cm^2

Since the base of a cylinder is a circle, then

50 = pi*r^2

15.9 = r^2

**r = 4.0 cm**(rounded to the nearest tenth)
