What are the coordinates of the center and the radius of the circle with equation (x - 4)2 + (y - 3)2 = 25 ?
Center (4, 3)
Radius = 5 units
Center (4, 3)
Radius = 25 units
Center (-4, -3)
Radius = 25 units
Center (-4, -3)
Radius = 5 units

4
8
4√2
2√2
A circle has the equation x2 + y2 - 12x + 8y + 3 = 0. Write the equation in standard form.
(x - 6)2 + (y + 4)2 = 49
(x + 4)2 + (y - 6)2 = 49
(x - 6)2 + (y + 4)2 = 55
x2 + y2 = 55
Find the center and radius of the circle: x2 + y2 + 14x - 2y = -1.
center = (-7, 2) radius = 3
center = (-7, 1) radius = 7
center = (-4, 1) radius = 7
center = (-4, 2) radius = 3
