How much leather is needed to cover the baseball?
How much rubber is needed to fill it?

You need to find the surface area and the volume. The formula for surface area is 4*3.14(pi)*radius^2 which is equal to 6.5144 inches^2 in this case. The amount of rubber needed to fill it is equal to the volume. The formula for volume of a sphere is 4/3*3.14(pi)*radius^3, just plug in the number (remember radius is half of diameter) and that will give you the answer!

The amount of leather needed to cover the baseball and the amount needed to fill it are respectively;  6.16 sq.in and 1.44 in³

What is the surface are and volume?

We have diameter = 1.4

Thus, radius; r = 1.4/2 = 0.7 in

A baseball is spherical in shape. Thus;

Surface area of baseball is;  A = 4πr.

Thus, the amount of leather required to cover the baseball is;

A = 4π * 0.7 = 6.16 sq.in

The amount of rubber needed to fill it is;

V = (4/3) * π(0.7)³ = 1.44 in³
