come on guys what if you got a remodel job and the home owner wanted an arch at these heights. if you cant do it then you should not be allowed to be a contractor. so many guys think they can do a job. but they really cant. and its sad to see them call themselves a contractor:laughing:

Not sure which answer that you are looking for. The actual radius or the tape measure method. In the past, I used the tape measure idea to figure the radii of cardboard arch templates scribed from the field.

The radius is probably more like 20' He is asking to calculate an arc chord
I have forgotten how to do this as I do it so rarely along with probably everyone else here except the op who probably just learned it and is trying to show off. By the way manny nice new name

Wow...this weirdo is spreading his quiz across at least three different threads

Span=10'-0"
Rise=1'-0"

thus
radius = 13'-0"

What is your purpose? Hey, since you know it all - I want to know an easy way to convert .mpg files from my Sony camera to whatever format iMovie uses.....and don't bother cut and paste.....I have thoroughly read the first 10 google returns.
