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
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.
