The implicit formula for a circle with center (h, k) and radius r is (x – h)^{2} + (y – k)^{2} = r^{2}. We're given the center and radius, so all we need to do is plug the information into the right places. (x – h)^{2} + (y – k)^{2} = r^{2} (x – (14))^{2} + (y – 54)^{2} = 64^{2} (x + 14)^{2} + (y – 54)^{2} = 64^{2} It's okay to keep the 64^{2} in that form.
