The diameter of a circle has length 12. The center is at (-5, 2). Give the equation of the circle.
(x + 5)2 + (y - 2)2 = 144
(x - 5)2 + (y + 2)2 = 36
(x + 5)2 + (y - 2)2 = 36
(x - 5)2 + (y + 2)2 = 12
What is the equation of the circle.
(x - 3)2 + (y + 4)2 = 9
(x - 3)2 + (y + 4)2 = 3
x2 + y2 = 9
(x - 1)2 + (y + 1)2 = 7
What is the center of the circle with equation x2 + y2 = 1?
(1, 1)
(0, 0)
(0,1)
