Answer:
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
