The volume of a sphere is given by the formula V = (4/3)πr³, where r is the radius.

Using this formula, we can calculate the volume of a sphere with a radius of 9 inches:

V = (4/3)π(9)³
= (4/3)π(729)
= (2916/3)π
= 972π

Therefore, the volume of a sphere with a radius of 9 inches is 972π cubic inches.

The correct answer is 972 π cubic inches.
