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
The volume of a sphere can be calculated using the formula V = (4/3)πr^3, where V is the volume and r is the radius of the sphere.
Given that the diameter of the basketball is 9 inches, the radius would be 9/2 = 4.5 inches.
Using the formula, the volume (V) of the basketball would be:
V = (4/3)π * (4.5)^3
V ≈ 381.7 cubic inches
Therefore, approximately 381.7 cubic inches of air would be needed to fill the basketball.
