Ok, pi is probably a bit over the head of your average 5 year old. I know the definition of pi is circumference / diameter, but is that really how we get all the digits of pi? We just get a circle, measure it and calculate? Or is there some other formula or something that we use to calculate the however many known digits of pi there are?

The most well known series that can be used is the sum of the reciprocals of squares of natural numbers, i.e. 1/n^2
This converges to Pi^2/6. With this you can calculate digits.
Sure, there are better series’, but I think this one is the most common one for people.
