The volume of a sphere is given by the formula V = (4/3)πr^3, where r is the radius of the sphere.
Since the diameter of the basketball is 9 inches, the radius is half of that, which is 4.5 inches.
Substituting the radius into the formula, we have V = (4/3)(3.14)(4.5)^3.
Calculating this expression, we get V ≈ 381.5 inches cubed.
Therefore, the answer is 381.5 in.3.
Use the formula for the volume of a sphere to solve the following problem.
How much air is needed to fill a basketball with a diameter of 9 inches? Use 3.14 as an approximation for pi. Round your answer to the nearest tenth.
