If the center is (1, 2) the circle has equation
(x − 1)^2 + (y − 2)^2 = r^2,
where r is the radius.

To find r use any point (x0,y0) on the circle and compute
r^2 = (x0 − 1)^2 + (y0 − 2)^2.

If you tell me one point on the circle (or upload the graph), I will compute the specific equation. (Example: if the circle goes through (4,2), then r^2 = (4−1)^2+(2−2)^2 = 9 and the equation is (x−1)^2+(y−2)^2 = 9.)
