Answer:
These two sections of the wire from a parallel combination of two resistances. Hence, the effective resistance between the two ends of any diameter of the circle is 1.25 Ω.

The length of the wire between two points at the ends of a diameter of a circle is half of the whole wire. The resistance of a conductor is directly proportional to its length.
- so it will be 1.25
