definition circle.
A circle is the set of points equidistant from a point C(h,k) called the center. The fixed distance r from the center to any point on the circle is called the radius. The standard equation of a circle with center C(h,k) and radius r is as follows. [latex] (x-h){^2} + (y-k){^2} = r{^2} [/latex] Reference. …
