the general equation of a circle is
%28x-x1%29%5E2+%2B+%28y-y1%29%5E2+=+r%5E2+ where (x1,y1) is the center of the circle and
r its radius
given
equation of the circle
+%28x-2%29%5E2+%2B+%28y+%2B+3%29%5E2+=+16+
rewriting this equation in the standard form
+%28x-2%29%5E2+%2B+%28y+-+%28-3%29%29%5E2+=+4%5E2+
clearly the centre is (2,-3) and the radius 4

(x-h)^2+(y-k)^2=r^2
(x-2)^2+(y+3)^2=16
h=2 k=-3 (2,-3)
