Comments:
To find the circumference of the Earth I found my distance from the equator by multiplying my latitude by 111 km (1 degree = 111 km) to get a distance of 3892 km from the equator. I than multipled that by 360 degrees and divided that number by my measured angle to get the earth's circumference.
