It is the distance across the entire span of the circle.
Draw a line from one side to the next side like a cord, except directly through the center so that the circle is split in 2 identical semi-circles. The length of this line is the diameter.
The radius of the circle is HALF the diameter so you have the relationships:
D = R/2
or
R = 2D
for R = the radius and D = the diameter
