WEBThe equation of a circle is x^2+y^2=r^2, x2 + y2 = r2, where r r represents the radius, with a center at 0,0 0,0 and (x-h)^2+ (y-k)^2=r^2, (x − h)2 + (y − k)2 = r2, where r r represents the radius, with a center at (h,k). (h,k). The definition of a circle is a set of all points on a plane that are a fixed distance from a center.
