The standard equation of a circle with center (h, k) and a vertical axis of symmetry is (x - h)2 + (y - k)2 = r2. A circle's center is (3, −2) and the radius is 12. Which equation models the circle? A)(x − 3)2 + (y + 2)2 = 12
B)(x + 3)2 + (y − 2)2 = 12
C)(x − 3)2 + (y + 2)2 = 144
D)(x + 3)2 + (y − 2)2 = 144
