X2 y2 = r2 x 2 y 2 = r 2 In this equation, r r is the radius of the circle A circle has only one radius—the distance from the center to any point is the same To change our circle into an ellipse, we will have to stretch or squeeze the circle so that the distances are no longer the sameFor example, follow these steps to graph the equation (x – 3) 2 (y 1) 2 = 25 Locate the center of the circle from the equation (h, v) (x – 3) 2 means that the xcoordinate of the center is positive 3 (y 1) 2 means that the ycoordinate of the center is negative 1 Place the center of the circle at (3, –1) Calculate the radius byThis means that, using Pythagoras' theorem, the equation of a circle with radius r and centre (0, 0) is given by the formula \ (x^2 y^2 = r^2\)
