This is not a circle: %28x%2B2%292+%2B+%28y-1%292+=+16.

THIS is a circle: highlight_green%28%28x%2B2%29%5E2+%2B+%28y-1%29%5E2+=+16%29.

The center is (-2,1) and the radius is 4, because 4%5E2=16


A circle equation in standard form is %28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2
and r is radius and center is (h, k).
