He was the first one to use the word geography and he also had a small-scale notion of the planet that helped him to determine the circumference of the earth. R=6370 3. By knowing the Equatorial diameter or the polar diameter of the Earth, the circumference can be found. This requires an elliptic integral to find, given the polar and equatorial radii: The rectifying radius is equivalent to the meridional mean, which is defined as the average value of M:[14]. It is with the values I gave you. The standard English name of the planet, including in science, is Earth. How many miles is a meter in scientific notation? In the third century B.C., Eratosthenes was able to mathematically calculate the earths diameter by comparing differences in the angle of the suns rays at two separate geographic points.
