Complete the square and write the equation in standard form. Then give the center and radius of the circle and graph the equation.x2 + y2 - 6y - 0 = 0
A. (x + 3)2 + y2 = 9
center (-3, 0), r = 3
B. x2 + (y - 3)2 = 9
center (0, 3), r = 3
C. x2 + (y + 3)2 = 9
center (0, -3), r = 3
D. (x - 3)2 + y2 = 9
center (3, 0), r = 3
