Question

Basketballs come in many different sizes and are measured by their circumference. The official size of the basketball used by the NBA is 29.5 inches in circumference. This translates to a diameter of approximately 4.7 inches. What is the volume of air a basketball of this size can hold? (Use 3.14 for π. Round your answer to 1 decimal place.)

Answer 1

Volume = 4πr^3/3

= 4 x 3.14 x 4.7/2 x 4.7/2 x 4.7/2 x 1/3

= 39.5 (approx.)

Hope this helps!
