Answer:
The sphere has a diameter of 32 in.
The radius’s length is one-half the length of the diameter.
Explanation:
The diameter is the measurement of the line that starts at one end of a circle or a sphere and ends at the other end.
The radius is half the diameter. The radius goes from one end of the circle or sphere to the center.
So, if a sphere has a radius of 16 inches, it would have a diameter of 32 inches.
16 * 2 = 32
I cannot see the volume of the sphere.

Using 3.14 for pi and 16 for 'r':

The volume of the sphere is about 17148 cubic centimetres.
