The Tropic of Cancer is 23.5 degrees north of the Equator. On a given day a vertical stick on the Equator casts no shadow while the one on the Tropic of Cancer does. Calculate the circumference of the earth using this information. (HINT: One degree of latitude is approximately equal to 111 km)

approximately 111km/degree x 360 degrees = approximately 39960 km

Using what information. If you know that 1 degree is 111 km then multiply it by 360 to get the circumference.
36000 + 3600 + 360 = 39960km
Your calculation should be based on the length of shadow of the stick at 23.5 deg N at Mid-day as compared to the actual length of the stick.

This is a stupid question because you don't need the Tropic of Cancer thing, whatsoever. Are you sure that is how the question is posed? Does not make sense for a well designed student exercise.

This happens at night-- right?
