The outer radius is 20/2 = 10 inches
The answer will depend on what is 20 inches: the radius or diameter or something else.
The radius would be 10 inches. Not sure about a radious, though.

20 inches will be the 'diameter' so the 'radius' will be 10 inches.
radius = 20/(2*pi) = 3.183098862 inches

The outer radius is 20/2 = 10 inches
The answer will depend on what is 20 inches: the radius or diameter or something else.
The radius will be half the diameter which is 20/2 = 10 inches
r = 3.18 inches.
The radius would be 10 inches. Not sure about a radious, though.
