That sounds very familiar!
Definition of terms:
http://en.wikipedia.org/wiki/Pi
http://en.wikipedia.org/wiki/Radius
Fascinating ... after plowing through some of that methinks
I'd rather roll out the cable and put a tape to it! ;-)
Seriously, years ago I had been given a couple of rolls
of fiber optic cable and a Christian missions organization
wanted to know the length prior to me paying to ship it to
them as a donation. At the time it made a whole lot more
sense to estimate the length using the formula versus
unrolling, measuring, and re-rolling the cables.
For those on this list the formula is valuable when considering
a roll of coax at a Fest or via the Internet.
