Answer: 381.51 cubic inches

Explanation:

We know that the shape of a basketball is sphere.

The volume of a sphere is given by :-

$V=(4)/(3)\pi r^3$ , where r is the radius of the sphere.

Given : The ball on the trophy has a diameter of 9 inches.

i.e. Radius = 4.5 inches [Radius is half of diameter and
(1)/(2)*9=4.5 ]

Then, volume of ball =
$(4)/(3)(3.14) (4.5)^3=381.51\ in^3$

Hence, volume of ball =381.51 cubic inches
