%28x-h%29%5E2+%2B%28y-k%29%5E2=r%5E2
center is at (h,k)
Given:
center at (0,3), so, h=0 and k=3
radius r=7
%28x-0%29%5E2+%2B%28y-3%29%5E2=7%5E2
x%5E2+%2B%28y-3%29%5E2=49
x%5E2+%2By%5E2%2B6y%2B9=49
x%5E2+%2By%5E2%2B6y=49-9
x%5E2+%2By%5E2%2B6y=40
x%5E2+%2By%5E2%2B6y-40=0......equation in general form
