Question

The radius of a basketball is 10 inches, and the radius of a soccer ball is 9 inches. How much greater is the volume of the basketball than the soccer ball? Round the nearest tenth.

Answer 1

1135.2

Explanation:

1135.2

Answer 2

The basketball volume is 1135.2 in³ greater than the soccer ball volume.

Explanation:

Basketball volume is V = (4/3)πr³, or V = (4/3)(3.14)(10 in)³ = 4188.79 in³

Soccer ball volume is V = (4/3)πr³, or V = (4/3)(3.14)(9 in)³ = 3053.63 in³

Subtract the smaller from the larger to determine how much greater the large ball volume is:

4188.79 in³ - 3055.63 in³ = 1135.2 in³
