(x + 9)^{2} + (y + 3)^{2} = 96

The general formula for the circle is (x - h)^{2} + (y - k)^{2} = r^{2}.

The center is at the point (h, k). **The center is (-9, -3)**. The circle is translated 9 units to the left and 3 units downward.

To find the radius of the circle, set r^{2} to 96. Square root on both sides to get **r = √96 ≈ 9.8 units**.
