Acity'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

This was correct on my test

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?

Correct

Correct 4500π ft3

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
