Can someone please explain to me how you get the equation:

radius=([tex]\sqrt{c}[/tex]+m

^{2})/2m

c=length of chord

m=distance from midpoint of chord to edge of the circle

I would like to find the radius of the circle from only knowing those two quantities.

I have found the equation on various websites across the web (including http://www.math.utah.edu/~eyre/rsbfaq/physics.html), but I do not know how it was derived.

Thanks,
