First the why, it was found, no matter the measured diameter of a given circle, that when the circumference was divided by the diameter the result was always 3.14. Making 3.14 a constant quotient. Second the how, it was found that the diameter is approx. a 3rd of the circumference of a circle. PI represents this ratio. So when we multiply this ratio by any given diameter it gives us the circumference of the given circle. This is really easy, isn’t it? Now you know some of the basic ideas around the amazing number PI also known as π. Let’s take a break from the serious stuff and learn the fun side of PI.
