 IN MATH: 1. n. chord through the center of a circle; a line segment with endpoints on the circle and which also contains the center of the circle. EX. The diameter of a circle is the hypotenuse of right triangle ABC with its right angle at C. Draw the circle and triangle. 2. n. length of the diameter.

Circle
Circles are describe in terms of their radius or diameter.
The circumference is the perimeter of a circle. The circumference,
in terms of radius, or
