You can do this by rearranging the equation into the format:
(x - a)2 + (y - b)2 = r2
Where (a, b) is the center of the circle, and r is it's radius. This can be done by completing the square separately for the x terms and for the y terms:
x2 + y2 - 8x + 2y = 110
∴ x2 - 8x + 16 + y2 + 2y + 1 = 110 + 16 + 1
∴ (x - 4)2 + (y + 1)2 = 127
So this circle has a center point of (4, -1), and a radius of √127, or just a hair more than eleven. It's area would be 127π, and it's circumference 2π√127
