Final answer:
The GMR (Geometric Mean Radius) of the unconventional conductor in terms of the radius r of 1.704r is approximately 117.8622 * r.
Step-by-step explanation:
The GMR (Geometric Mean Radius) can be found by taking the square root of the product of the three strand radii.
GMR = √(1.704r * 1564r * 1.764r)
GMR =√(1.704 * 1564 * 1.764) * r
GMR ≈ 117.8622 * r
Therefore, the GMR in terms of the radius r of 1.704r would be approximately 117.8622 * r.
