In order to graph a circle we must first determine the equation of the circle.

There are two equations of the circle that must be taken note:

Equation of the circle with the center at the origin.

x^2 + y^2 = r^2

Equation of the circle with the center at any points(h,k), where h is the x point, and k is the y point.

(x - h)^2 + ( y - k )^2 = r^2

The points determine the center of the circle, and by taking the square root of r^2, we can determine the radius of the cirlce.
