A solid plastic ball is a sphere with radius 2 in. How much plastic does it take to make one ball? Use 3.14 for pie

Answer 1

To find out how much plastic it takes to make one ball, we need to calculate its surface area.

The surface area of a sphere can be found using the formula:
surface area = 4 * π * radius^2

Given that the radius of the ball is 2 inches, we can substitute the value into the formula:
surface area = 4 * 3.14 * 2^2
surface area = 4 * 3.14 * 4
surface area = 50.24 square inches

Therefore, it takes 50.24 square inches of plastic to make one solid plastic ball with a radius of 2 inches.
