Answer:

Area, [tex]A=69.21\ \text{inches}^2[/tex]

Step-by-step explanation:

We have,

The diameter of a basketball is 9.39 inches.

It is required to find the number of square inches of material used in constructing a basketball. It means we need to find the area of basketball. It is given by :

[tex]A=\pi r^2[/tex]

r is radius of basketball, r = 4.695 inches

So,

[tex]A=3.14\times (4.695)^2\\\\A=69.21\ \text{inches}^2[/tex]

So, the area of the basketball is [tex]69.21\ \text{inches}^2[/tex].
