Explanation:-

Eratosthenes divided 360° by 7.2° and got 50, which told him that the distance between Alexandria and Syene (500 miles) was 1/50 of the total distance around the Earth. So he multiplied 500 by 50 to arrive at his estimate of the Earth’s circumference: 25,000 miles. This estimate was only 100 miles off the actual circumference of 24,900 miles!
