you need to find the circumcenter of the triangle and that will be the center of the circle that circumscribes it.


once you find the center, you should be able to derive the equation of the circle, the general form of which is (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the centerof the circle and r^2 is the square of the radius of the circle.
