The general equation is
(x − 7)^2 + (y − 2)^2 = r^2
where r is the radius.

To find r you need one point (x1,y1) that lies on the circle (read any point on the circle from the graph). Then
r = sqrt[(x1 − 7)^2 + (y1 − 2)^2],
and plug r^2 into the equation.

If you tell me one point on the circle (or upload the graph), I will compute r and give the specific equation.
Example: if the circle passes through (10,6) then r = sqrt((10−7)^2+(6−2)^2) = 5 and the equation is (x−7)^2+(y−2)^2 = 25.
