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
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.
