    Question Please help this problem is driving me crazy

    Your planet has a circumference of 44032 miles at the .918 latitude North. If it takes 2.5 earth days (24 hour days) for your planet to complete one rotation then determine the following:

    I got the radius its 7007.910 miles. Now its asking for the circumference of the equator. How do I find the circumference of the equator? Oh yes this is my first trig. class so I'm not advanced or anything. Thanks!

    Oh thanks VonNemo19, sorry I wasn't paying attention I could have figured that out. I have to find the angular velocity at the latitude how do I do that? I got .160 for the latitude in radians. Its supposed to be in radians/earth hour.

    \omega=\frac{\theta}{t}

    In your case \omega=\frac{2\pi\mbox{rad}}{2.5(24)\mbox{hr}}

    angular velocity is independent of latitude.
