Forgot a formula.......

[Larry Edgerton]

I had all the formulas I use written on the wall in my old shop, and they painted the wall before I copied them.

I need the formula for finding the radius of a partial circle when you have the bottom cord and the height to the top of the arch.

Thanks, and good charma to the one who answers. You may want to run out and buy a lottery ticket after you answer!:)

I believe it is 1/2 cord squared + the height squared divided by 2 times the height.

This is correct and pluperfect in that it is the shortest version of this formula.

Spell check not working?

I believe it is 1/2 cord squared + the height squared divided by 2 times the height.

Thanks Walter. I thought I could remember but wanted confirmation. Go get that lottery ticket....
