%28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2 is the circle equation with center (h,k) and radius r.


In this case, (h,k) = (7,-2) and r = 16


%28x-h%29%5E2+%2B+%28y-k%29%5E2+=+r%5E2


%28x-7%29%5E2+%2B+%28y-%28-2%29%29%5E2+=+16%5E2


%28x-7%29%5E2+%2B+%28y%2B2%29%5E2+=+256


-------------------------------------------------------


The answer is %28x-7%29%5E2+%2B+%28y%2B2%29%5E2+=+256
