Explore the interactive activity and answer the questions that appear below the applet.
Suppose P(x,y) = any point that lies on a circle with center (h,k) and radius r, where r > 0.
Use what you've observed to write an equation that expresses the relationship among x, y, and r.
(No need to square any binomial expressions!)
