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.

Question

(Round to the nearest hundredth as needed.)

Answer 1

To calculate the amount of plastic it takes to make a solid plastic ball, we need to find its surface area.

The formula for the surface area of a sphere is given by: A = 4πr², where A is the surface area and r is the radius of the sphere.

Given that the radius is 2 inches, we can substitute this value into the formula to find the surface area of the ball:
A = 4 * 3.14 * (2)^2
= 4 * 3.14 * 4
= 50.24

Therefore, it takes approximately 50.24 square inches of plastic to make one ball.
