Circles are of the form %28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2 with center (h,k) and radius r.


We're given "center (-3,7) and radius is 12", so (h,k) = (-3,7) ----> h = -3, k = 7 and r = 12


Plug these values in:


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


%28x-%28-3%29%29%5E2%2B%28y-7%29%5E2=12%5E2


%28x%2B3%29%5E2%2B%28y-7%29%5E2=144


and that's your final answer
