      I assume you are asking the Greek letter Pi, π

      Before I say anything further, let’s recall all circles have a circumference, diameter and radius:

      The circumference is the distance all the way around a circle.

      The diameter is the distance right across the middle of the circle.

      The radius is the distance halfway across the circle. The radius is always half the length of the diameter.

      Pi is an endless number starts with 3.14159…This magic number is the ratio between the diameter and circumference of all circles.

      For example, the diameter of a circle is 1 cm, the circumference of that circle is 1 cm x Pi = 3.14159…cm
