The radius is the distance from the centre to the edge, in a straight line.
The diameter is that line continued from the centre to the edge, in the opposite direction.
So a radius of 2 inches means a diameter of 4 inches.

Two inches. The radius of a circle is 1/2 of the diameter.
The diameter of any circle is twice its radius. A circle with a radius of 13 inches will have 2 x 13 = 26 inches for a diameter.
Radius = diameter/2 = 24 inches
6 inches. always multiply radius by 2 to get diameter
Radius is merely..., diameter/2 3 inches/2 = 1.5 inches in radius ==============
