To find the amount of plastic needed to make the solid plastic ball, we need to calculate its surface area. The surface area of a sphere is given by the formula A = 4πr^2.
Given that the radius of the sphere is 11 inches, we can substitute this value into the formula:
A = 4π(11^2)
A = 4π(121)
A ≈ 484π
Approximating π to 3.14, we get:
A ≈ 484 * 3.14
A ≈ 1521.76
Therefore, it would take approximately 1,521.76 square inches of plastic to make one ball.
A solid plastic ball is a sphere with radius 11 in. How much plastic does it take to make one ball? Use 3.14 for pie
