cubic inches of candy does polly need?

Answer 1

The volume of candy that is needed by Polly is 1,437.3 cubic inches

Explanation:

What we have to do here is to find the volume of the sphere with a diameter of 14 inches

If the diameter is 14 inches, then the radius is 14/2 = 7 inches

This is because the radius is half the measure of the diameter

To find the volume of the sphere, we use the formula below;

Volume of sphere

= 4/3 * pi * r^3

pi = 22/7

r = 7 inches

Volume is;

4/3 * 22/7 * 7^3

= 4/3 * 22 * 7^2 = 1437.3 cubic inches
