Write the equation of the circle in standard form. Find the center and radius. Then sketch the graph.x2 + y2 - 12x + 32 = 0
A. (x + 6)2 + y2 = 4
(h, k) = (-6, 0), r = 2
B. (x - 6)2 + y2 = 4
(h, k) = (6, 0), r = 2
C. x2 + (y - 6)2 = 4
(h, k) = (0, 6), r = 2
D. x2 + (y + 6)2 = 4
(h, k) = (0, -6), r = 2
