... and for a long time, I took this for granted, but now I'm starting to wonder how it is doing this. From my knowledge, the only way one could calculate pi is to measure the diameter and radius of a circle, and find the ratio, but to calculate an irrational decimal as thoroughly as we have would require an unrealistically accurate measurement. There may be some sort of equation that can be used to calculate pi, but I have no idea what it is.
So, how are mathematicians managing to calculate pi?
