Question

Find the surface area of a basketball with a diameter of 10 in.

10 in
o 100T in
o 400T in
o 25T in?
o 10T in?

Answer 1

100 pi in ^2

Explanation:

The surface area of a sphere is

SA = 4 pi r^2

We need to find the radius

r = d/2 = 10/2 =5

SA = 4 * pi * (5)^2

= 4 * pi *25

= 100 pi in ^2
