Write a equation of each circle.

We   need to find the radius......this is given by

sqrt [ (-2 - - 3)^2  + ( -3 - 3)^2  ]   =  sqrt [ 1^2 + (-6)^2]  =  sqrt(37)

So.........the equation is :

(x - x coordinate of the center)^2 + (y - y coordinate of the center)^2  =  radius^2

(x - - 3)^2  + ( y - - 3)^2   = 37

(x + 3)^2  + ( y + 3)^2   = 37
