Elementary set theory problem

  1. Oct 24, 2004 #1
    Let C be a circle and let D be the set of all diameters of C. What is [tex]\cap[/tex]D?

    I think it is the center of the circle since that would be the only point of intersection of all the diameters of the circle. Could someone let me know if I am correct?

    Do you have any thoughts as to how you could go about proving it?
