holdennut:
Does anyone know the formula that is used to calculate the radius of the arc in the picture below?

I have seen it before somewhere, using the distance between the two points of the arc and the height to that line and something about dividing by 8 ???

Any help would be appreciated.

Cheers Dustin, that's the one but I can't get it to work. What does ^ represent? (multiply, divide)

                4h^2 + c^2
       r   =  ----------------
                      8h

h = 95
c = 685
r = ?

Maybe I'm having a blond moment but every way I twist it the result is way off.

Cheers
