Find the length of wire in the given circular arrangement.

1. Length of wire = 2πr
2. Length of wire = πr
3. Length of wire = 2πr (0.1)
4. Length of wire = 0.2m

Correct answer: Length of wire = 2πr

Solution

The length of wire equals the circumference of the circle, calculated using the formula 2πr, where r is the radius.
