WebJul 3, 2024 · The diameter of a circle, by contrast, is the longest distance from one edge of the circle to the opposite edge. The diameter is a special type of chord, a line that joins any two points of a circle. The diameter is twice as long as the radius, so if the radius is 2 inches, for example, the diameter would be 4 inches.
