    Even easier than that is to draw the circle with the dividers, then
    place the pointed leg somewhere on the circumference, draw an arc,
    place the pointed leg on the place where the arc crosses the circle,
    then do this again with the other intersection -- the arcs will all
    intersect at the center of the circle. 

    Of course, even simpler yet; the spot where you placed the pointed
    leg to draw the circle, is the center. 

    But of course, this does not answer the original question, which has
    the "circle" already drawn, so to speak.
