Can anyone tell me how to set up the equation to find out how far it is around the Earth at the Equator? Tomorow I have to mail off a PHS 111 lab that is due, so any immediate help anyone could offer would be greatly appreciated. THANKS!!!!!!!!

Hello,
you can use another method:
If you know the distance between 2 points on a circle of longitude or the equator then you can calculate the circumference by:
d : difference of degrees
D: distance between the 2 points in km
then
Example:
First point on the equator at 10°W
Second Point on the equator at 16° W
Distance 667.9 km
