Complete the square and write the equation in standard form. Then give the center and radius of the circle.x2 + y2 - 18x + 2y + 82 = 4
A. (x + 1)2 + (y - 9)2 = 4 (-1, 9), r = 2 B. (x - 9)2 + (y + 1)2 = 4 (-9, 1), r = 4 C. (x + 1)2 + (y - 9)2 = 4 (1, -9), r = 4 D. (x - 9)2 + (y + 1)2 = 4 (9, -1), r = 2
