hi

i am trying to find equation of a circle passing through 2 points (x1,y1) and (x2,y2) using solve. i want the center of the circle (x0,y0). the input is Reduce or Solve[{(x1 - x0)^2 + (y1 - y0)^2 == r^2, (x2 - x0)^2 + (y2 - y0)^2 == r^2}, {x0, y0}]

but it gives me a huge and confusing output.
pls help how to get equations of x0 and y0 as a function of x1,x2,y1,y2.
