WebRadius of Circle Equation. The radius of a circle equation on the cartesian plane with center (h, k) is given as (x − h) 2 + (y − k) 2 = r 2. This is known as the equation of a circle when the radius is known. Here, (x, y) are the points on the circumference of the circle that is at a distance ‘r’ (radius) from the center (h, k).
