I am unsure how to find the moment of inertia for this problem it seems like it would be a ring but I am unsure.

One way to provide artificial gravity (i.e., a feeling of weight) on long space voyages is to separate a spacecraft into two parts at the
ends of a long cable, and set them rotating about their center of mass. A craft has been separated into two parts with a mass of 77100
kg each, at the ends of a cable with their centers of mass 178 m apart, rotating around the center point of the cable with a period of 390
seconds.
