We know that,
Circumference of the wire = 2πr
Thus, resistance per unit volume of the wire = 4/2πr = 2/πr
So, resistance of the specimen = 2/πr × 2r = 4/π
And resistance of the halves of the wire = 2/πr × πr = 2
Now, Equivalent resistance will be decided as 4/(4+π) as 4/π,2,2 are in parallel combination.

How do you calculate copper wire resistance?
if we know resistivity of copper i.e is very small (1.68×10−8)transposing the definition to make resistance the subject (Pouillet's law):R is the electrical resistance of a uniform specimen of the material (measured in ohms, Ω) is the length of the piece of material (measured in metres, m)A is the cross-sectional area of the specimen (measured in square metres, m²).
