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.
(Round to the nearest hundredth as needed.)
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.
