    A circle has a center at (6, 2) and passes through (9, 6)

    A circle has a center at (6, 2) and passes through (9, 6) The radius (r) is found by using the distance formula to get: r = 5 And the equation of the circle is found by using the center (h, k) and radius r as: (x - h)^2 + (y - k)^2 = r^2 (x - 6)^2 + (y - 2)^2 = 5^2 (x - 6)^2 + (y - 2)^2 = 25
