If I told you to imagine a square. Importantly, I want you to pick any size of square that you like. As small or as big as you want. And you end up randomly selecting a size.
Now draw the biggest circle that you can inside of that square. IE each inner side of the square should be touched by the edge of the circle.
Now draw the smallest circle that you can around the outside of the square. IE The circle should touch each corner of the square.
Now, if I told you to add up the two circumferences of those circles and your answer ended up being 99.99% accurate to the most important universal constant that we know of, would you agree that the precise size of initial square that you chose was extremely coincidental? Especially if the answer was a very large number.
Because remember, the size of square that you randomly chose, that's what would determine your final answer. So it's not some trick where you always end up with the same answer.
