Answer:

Explanation:

A basketball is basically a sphere, so it suffices to calculate the surface are of the ball to determine the amount of required material. Given a sphere of radius r we have that the surface area is
$4\pi r^2$

In this case, r = 11.14 cm. So the area is aproximately 1159.48 squared cm. (1159.48 =
$4\pi (11.14)^2$ )
