Vh
I did not know it was lost! It is very important for the calculation of the area of a circle and such calculations were important to the ancient geometers (people who measured land/earth).
Lets pretend that the Earth is a perfect sphere. Surface area of a sphere = 4(pi)(radius)^2. The radius of earth is 6378.1 km. Plug that into your equation and you'll get your answer.
