Question

Solve each problem. Use 3.14 for p.

1. The diameter of a small red beach ball is 8 inches. Calculate the volume of the red beach ball to the nearest whole number.

Answer 1

268 in³

Explanation:

Radius = 8/2 = 4 inches

Volume = (4/3)×3.14×4³

= 267.9466667 in³

Answer 2

V = 268 inches^3

Explanation:

The volume of a sphere is V = 4/3 pi r^3

The diameter is 8 so the radius is d/2 = 8/2 = 4

V = 4/3 (3.14) 4^3

V = 267.946666667

Rounding to the nearest whole number

V = 268 inches^3
