Question

How many cubic inches of plastic needed to fill the mold?

Answer 1

C. 36π

Explanation:

The formula for volume of a sphere is:

V=⁴/₃πr³

We are given diameter: 6

To convert to radius, divide by 2.

6÷2=3. R=3

Plug in to formula

V=⁴/₃π3³

Simplify with multiplication

V=⁴/₃π27

V=36π
