Question

The diameter of a basketball is approximately 9 inches. What is its volume? Round your answer to the nearest whole number.

A. 339in^3
B. 38in^3
C. 3052in^3
D. 382in^3

Answer 1

V ≈ 382 in^3

Explanation:

1. Volume of a sphere

`V=(4)/(3)\pi r^(3)`

2. Get radius

r = d/2

r = 4.5

3. Plug in and solve

`V=(4)/(3)\pi 4.5^(3)`

`V=381.7`
