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?

It’s a little hard to ELI5 without involving formulas unfortunately!
To calculate Pi, we use a simple formula that relates the circumference and diameter of a circle. The formula is: Pi = C/d, where C is the circumference (the distance around the circle) and d is the diameter (the distance across the circle, passing through the center).
To use the formula, we just need to measure the circumference and diameter of a circle. We can do this with a ruler or a tape measure, or with more precise tools, like a caliper or a micrometer. Then we divide the circumference by the diameter to find the value of Pi. For example, if the circumference is 10 inches and the diameter is 3 inches, then Pi = 10/3 = 3.33.
The value of Pi is the same for all circles, no matter how big or small they are. This is because the formula for Pi is based on the basic properties of circles, like their symmetry and their geometric relationships. The value of Pi is also an irrational number, which means it can’t be written exactly as a fraction or decimal, but it can be approximated to any level of precision.
