How much air of 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 tenths.
The formula for the volume of a sphere is V = (4/3)πr^3.
Since the diameter of the basketball is 9 inches, the radius will be half of that, which is 4.5 inches.
Using the formula, we can calculate the volume of the basketball:
V = (4/3) * 3.14 * (4.5)^3 = 381.4 cubic inches.
Therefore, approximately 381.4 cubic inches of air is needed to fill the basketball.
