Answer: 381.51 cubic inches
Step-by-step explanation:
We know that the shape of a basketball is sphere.
The volume of a sphere is given by :-
[tex]V=\dfrac{4}{3}\pi r^3[/tex], 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 [tex]\dfrac{1}{2}\times9=4.5[/tex] ]
Then, volume of ball = [tex]\dfrac{4}{3}(3.14) (4.5)^3=381.51\ in^3[/tex]
Hence, volume of ball =381.51 cubic inches
