Question

Use the formula for the volume of a sphere to find the volume of a basketball that has a diameter of 9.2 inches. Use 3.14 as an approximation for pi and round your answer to the nearest hundredth, if necessary.(1 point)

407.51 in.3


1,222.54 in.3


3,260.11 in.3


115.55 in.3

Answer 1

Use V = (4/3)πr^3. Diameter = 9.2 so r = 4.6.

r^3 = 4.6^3 = 97.336
V = (4/3)(3.14)(97.336) = 407.513... ≈ 407.51 in^3

Answer: 407.51 in.^3 (first choice).
