A tennis ball has a diameter of 3 inches to the nearest tenth find the number of cubic units the tennis ball occupies

14.1 in³

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3) πr³. Here the radius (r) is half the diameter, that is, half of 3 inches, or 1.5 inches.

Thus, the volume of the ball / sphere is V = (4/3) π (1.5 inches) ³. Find (1.5 inches) ³ on a calculator (it is 3.375 inches³). Then multiply this result by (4/3) π:

V = (4π/3) (3.375 inches³) = 14.1 in³
