WebTo calculate the circumference of a circle, use the formula C = πd, where “C” is the circumference, “d” is the diameter, and π is 3.14. If you have the radius instead of the diameter, multiply it by 2 to get the diameter. You can also use the formula for circumference of a circle using radius, which is C = 2πr. WebThe actual polar circumference of Earth is just a bit over 40 thousand km (about 24,860 miles). Eratosthenes was a talented mathematician and geographer as well as an astronomer. He made several other important contributions to science. Eratosthenes devised a system of latitude and longitude, and a calendar that included leap years.
