1 A circle is all of the points that are a fixed distance, known as the radius, from a given point, known as the center of the circle. 2  Explore the standard equation of a circle using the applet below (Go here for a larger version).
From the equation, get the fixed point and the given distance. The general form for the equation of a circle is: (x - (h))^2 + (y â (k)^2) = r^2 That is needed to get the center and the radius. From the center point, find points that are r distance away and plot them.
