To find the volume of the basketball, we can use the formula for the volume of a sphere: V = (4/3)πr^3.
Since the diameter of the basketball is given as 9 inches, the radius would be half of that, which is 4.5 inches.
Substituting the values into the formula, we get V = (4/3) × 3.14 × (4.5)^3 ≈ 381.5 inches cubed.
Therefore, the answer is 381.5 inches cubed.
