Folks -

*Somewhere* there was an online calc or website that was able to figure out
the length of the segments in creating a circle of "X" inches in diameter.
I am sure that many of you math types will guffaw, so I'll take my lumps,
but I'd like a better way than laying it out on paper and measuring.

I was showing one of the students how to lay out an 8 and also a 12 sided
circle, 12" in diameter, with 3" wide stock. Our method worked okay and
all, I just know that there's an easier way to do it.

Any ideas??
