A solid plastic ball is a sphere with radius 14 in. How much plastic does it take to make one ball? Use 3.14 for pie

Answer 1

To find the amount of plastic it takes to make one ball, we need to calculate the surface area of the sphere.

The surface area of a sphere is given by the formula:

Surface Area = 4πr^2

Given that the radius of the ball is 14 in, we can substitute it into the formula:

Surface Area = 4 * 3.14 * (14^2)

Calculating this gives:

Surface Area = 4 * 3.14 * 196

Surface Area = 2463.52 square inches.

Therefore, it takes approximately 2463.52 square inches of plastic to make one solid plastic ball with a radius of 14 inches.
