To solve this problem, you first need to find the circumference of the given coil.
To do this, multiply the specified value of the diameter by a constant number P, which is approximately 3.14.
Will be:
5 cm = 5/100 = 0.05 m.
3.14 * 0.05 = 0.157 m.
Thus, since the number of turns of wire is 20, the total length of the wire will be:
0.157 * 20 = 3.14 meters.
Answer: The wire length is 3.14 meters.
