Question

What is the radius of a sphere with a volume of 7961 cm", to the nearest tenth of a

centimeter?

Answer 1

12.4 cm

Explanation:

Use the sphere volume formula, V =
`(4)/(3)`
`\pi`r³

Plug in the volume and solve for r, the radius:

V =
`(4)/(3)`
`\pi`r³

7961 =
`(4)/(3)`
`\pi`r³

1900.55 = r³

12.39 = r

So, the radius of the sphere is approximately 12.4 cm
