Question

11. Matt brings twelve basketballs to the park for practice. The diameter of the basketball is 9.5

inches. How much cubic inches of air will you need to fill all the basketballs?
(Round to the nearest hundredth.)

Answer 1

Answer: 5387.05
`in^3`

Explanation:

9.5 / 2 = 4.75 (Radius of 1 Basketball)

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

V = (4 x π x 4.75^3) / 3

V = 1346.761 / 3

V = 448.92

Thus we need 448.92
`in^3` to fill 1 basketball

12 Basketballs = 449.92 * 12

12 Basketballs = 5387.046 ≈ 5387.05
