Longitude: 78.9267250 W
Distance to Equator: 10750
Measured shadow angle in degrees: 85
Calculated Earth circumference: 45,529 km
Comments:
I compared my results to the actual circumference of the Earth and I think my measured angle was about 10 degrees off. This was a pretty interesting experiment. A wonder how Eratosthenes found out this information with only rudimentary tools and his own ability to figure out the calculation.
