Asked by Don
If the center of a circle is at
(2,2) with a radius of 4 the equation of the graph would be :
a) (x-2)^2 + (y-2)^2 = 16
b) (x+2)^2 + (y+2)^2 = 16
I think it would be b
is that correct?

I would put my money on a)
for centre (h,k) and radius r, the equation of the circle is
(x-h)^2 + (y-k)^2 = r^2
for centre (h,k) and radius r, the equation of the circle is
(x-h)^2 + (y-k)^2 = r^2
