How do you find the length of a coil of wire without unraveling it?

You know that each 'wrap' or turn of wire in the coil has to go all the way around
the coil-form, and you know how to calculate the distance around a circle. So all
you have to do is count the number of times the wire goes around the coil, measure
the coil's diameter, calculate its circumference, and multiply that by the number of
turns in the coil.
