= 730.4?

(b) Calculate the time taken by the satellite to complete on revolution of the Earth

Someone pls, tell me what i should do here? StepbyStep? Thanks.

Use Kepler's Law to calculate the period.

Use Kepler's Law to calculate the period.

Correct me if i'm wrong. Period = T = 105.6 hours?

You need to use SI units in the formula, so your units should be in seconds for time.
