Solution

We know that the standard/center-radius form of the equation of a circle with the center at the point (h, k) and the radius r is (x – h)² + (y – k)² = r². Here, the center of the given circle is (-1,-1) and the radius is (8+6)/2 = 7. Hence the standaerd equation of the given circle is (x+1)²+ (y+1)² = 49.
