how much air is needed toa fill a basketball with a diameter of 9 inches use 3.14 for pi round your answer to the nearest tenth

The volume of a sphere can be calculated using the formula V = (4/3) * π * r^3, where r is the radius of the sphere.

Given that the diameter of the basketball is 9 inches, the radius would be half of that, which is 4.5 inches.

Plugging the radius into the formula, we get:

V = (4/3) * 3.14 * (4.5)^3
V ≈ (4/3) * 3.14 * 91.125
V ≈ 381.93 cubic inches

Therefore, approximately 381.9 cubic inches of air is needed to fill the basketball.
