# Math Help - Angular velocity problem

1. ## Angular velocity problem

A planet takes 60 hours to rotate and the radius of the equator is 7007.910 miles and the circumference of the equator is 14015.820 miles. How would I find the angular velocity of the equator? Is it just 2pi/60hours since one complete rotation is 2pi?

the angular velocity of any point on the planet (except its poles) is just $2\pi$ radians per 60 hours
