π (sometimes written pi) is a mathematical constant that is the ratio of a circle’s circumference to its diameter. π is approximately equal to 3.14. Many formulae in mathematics, science, and engineering involve π, which makes it one of the most important mathematical constants.[1] For instance, the area of a circle is equal to π times the square of the radius of the circle. (copied from wiki;)

He said “take a circle of any size and divide it by it’s own radius = PI”, (he never said circumference or diameter) I know he was talking about the circumference when referring to a circle being able to be any size though.

I don’t play with protractors or care about circles LOL, but it seems to me you would need something to be dividing something into. I know a circumference is the length around one, the diameter is a straight line through one, and the radius is from it’s center out to the edge.

Anyways, you cannot find pi from only using the radius and diameter (1inch divided by .5inch does not = pi LOL, meaning it’s circumference has to be used when finding pi.

Therefore it’s the circumference and diameter that are used when finding pi as wiki says, so I guess he confused radius with diameter on accident I would hope. LOL.

Now I can make a living from betting uninformed people that the diameter of any circle any size, divided by it’s circumference = pi (3.14) oh the joy. I find it strange that it’s true, however it probably makes perfect sense to the guy who first realized it. My question would be if you already know the answer, why ask the question? So when in school, when they told me here’s 100 circles divide the circumferences with their diameters, I would question what’s the point, they are all pi, then I would get an F for not showing work.

Also; the circumference and diameter are directly related to each other which explains why it is always 3.14 on any sized circle. When one # changes so do the rest. Making it not so strange, but still amazing it works that precise. It’s certainly is not magic.

It’s a little more than that.
