(x + 9)2 + (y + 3)2 = 96
The general formula for the circle is (x - h)2 + (y - k)2 = r2.
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 r2 to 96. Square root on both sides to get r = √96 ≈ 9.8 units.
