Question

A city's water tower is in the shape of a sphere with a radius of 15 feet. If the tank is full, what is the exact value of the volume of the tank?

A 225π ft3

B 450π ft3

C 550π ft3

D 4500π ft3

Answer 1

Volume = (4/3) * pi * r^3

            =   4/3 * pi * 15^3

            = 4500 pi 

D
