    Cool geometry

    Chords AB and CD of a circle intersect at E and are perpendicular to each other. Segments EA, EB and ED are of lengths 2 cm, 6 cm and 3 cm respectively. Then, what is the diameter of the circle ?

    Re: geometry

    Hi,
    The answer is \sqrt{65}. In the future if you want more information about a solution, show what you have tried. This is a help forum, not an answering service.
