Find the volume of the sphere with a radius of 9. express your answer in terms of π.

The volume of a sphere refers to the number of cubic units that will exactly fill a sphere. The volume of a sphere can be found or calculate by using the formula V=4/3πr^3, where r represents the radius of the figure.

On this exercise is given the radius of the sphere and is asked to find its volume in terms of π. The first step would be substitute the values into the previous mention formula.

V=4/3πr^3
V=4/3π(9)^3
V=4/3π(729)
V=972π 

The volume of the sphere in terms of pi is 972π.
