Answer:


Length = 9558.7\ mils

Step-by-step explanation:

Given


diameter = 82.2\ mils


Strands = 37

Required

The length of the wire

First, we calculate the circumference (C) of 1 strand of the wire


C = \pi d


C = (22)/(7) * 82.2


C = (22* 82.2)/(7)


C = (1808.4)/(7)

The length of the 37 strands is:


Length = 37 * C


Length = 37 * (1808.4)/(7)


Length = (37 * 1808.4)/(7)


Length = (66910.8)/(7)


Length = 9558.68571429


Length = 9558.7\ mils --- approximated
