Question

Calculate the amount of leather needed to manufacture a basketball if it has a radius of 11.14 cm. I need ASAP please and thank uuu

Answer 1

Answer:

Step-by-step 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 = $4\pi (11.14)^2$)
