Help with this one question?

The planet Jupiter's largest moon, Ganymede, rotates around the planet at a distance of about 656,000 mi, in an orbit that is perfectly circular. If the moon completes one rotation in 7.15 days, find the angle (theta) that the moon moves through in 1 day, in both degrees and radians. Round to 2 decimals and use exact values where possible. Please show how to work this out!
