Question 29470: If Eratosthehne were alive in the U.S. today, he could repeat his calculation of the circumference of Earth. Wichita, Kansas, is 345 miles due north of Fort Worth, Texas. At a given moment, the sun is 5 degrees lower in the sky in Wichita than Fort Wroth. From this information, what estimate would Eratosthenes obtain for the Earth's circumference?
