STANDARD EXPECTATION:  To show that the eqation of a circle with center at the origin and radius r is x^2 + y^2 = r^2 and determine the equataion for the graph of a circle with radius r and center (h, k), (x - h)^2 + (y - k)^2 = r^2.

SUCCESS CRITERIA:  I can show that the eqation of a circle with center at the origin and radius r is x^2 + y^2 = r^2 and determine the equataion for the graph of a circle with radius r and center (h, k), (x - h)^2 + (y - k)^2 = r^2.
