Which equation represents a circle with a center at (-3,-5) and a radius of 6 units?
(x - 3)2 + (1 - 5)2 = 6
(x - 3)2 + (y - 5)2 = 36
(x + 3)2 + (y + 5)2 = 6
(x + 3)2 + (y + 5)2 = 36

(x +3)^2 + (y + 5)^2  = 36

Step-by-step explanation:

Use general circle equation:

(x - h)^2  + (y - k)^2  = r^2

center:  (h, k)

radius : r

(x - (-3))^2 + (y - (-5))^2  = 6^2

(x +3)^2 + (y + 5)^2  = 36
