What is called radius?

Radius of a circle is the distance from the center of the circle to any point on it’s circumference. It is usually denoted by ‘R’ or ‘r’. This quantity has importance in almost all circle-related formulas. The area and circumference of a circle are also measured in terms of radius. Circumference of circle = 2π (Radius)
