To calculate the volume of a sphere, you can use the formula V = (4/3) * pi * r^3, where r is the radius of the sphere. In this case, since the basketball has a diameter of 9 inches, the radius would be half of that, which is 4.5 inches.
Plugging in the values into the formula, we get V = (4/3) * 3.14 * 4.5^3 = 3,052.1 inches cubed.
Therefore, the correct answer is 3,052.1 in.3.
