a. If you flew around Earth by following the equator at a height of 10 kilometers, how many trips around the Moon could you take in the same amount of time, at the same height from the Moon and a t the same speed? Explain

b. The circle whose circumference is the equator is sometime call the ?great circle? of Earth or of the Moon. Use a ratio to compare the areas of the great circles of Earth and the Moon.

trip around earth is pi*(12742+10) = 40061 km

trip around moon is pi * (2476+10) = 7810 km

so, what's 40061/7810?

b. ratio of great circles is the same as the ratio of the radii, since C = 2pi*r
