Solution: The center of circle is: X0=2+2/2=2 and Y0=-7+1/2=-3, center is (2,-3)
and
+d=+sqrt+%28%282-2%29%5E2%2B%281%2B7%29%5E2%29, d=8 and r=4 As we know the equation of circle
Centered at (X0,Y0) and radius r is: %28X-X0%29%5E2%2B%28Y-Y0%29%5E2=R%5E2
Substituting our given results: %28x-2%29%5E2%2B%28y%2B3%29%5E2=16 is the equation of circle.
