I've got a survey program in my HP48GX but I'm not sure even it will back
calc. the radius from arc and chord. Problem is their difference is so slight
that lots of error would creep in, probably more accurate to use chord and
middle ordinate.
Instead of a program which is probably gonna be hard to find I'd just measure
the length and chord or middle ordinate or whatever you can measure then take
the measurement to a large enough space to tape in the missing radius and see
what fits...DaveBranum
