    pi is used in finding rotations of circles and such, yes it is 3.141592..........

    One possible interpretation of pi is the ratio of the circumference to the diameter. If we took a string and placed it over the diameter and measured that length, and then wrapped it around the circumference and measured; we could take the quotient of the two in order to approximate this ratio. :) With more math: \(C = \pi d \to \frac{C}{d} = \pi \) by a division.

    |dw:1359577257770:dw|This is how I like to interpret pi, it's a little silly though :) If you think of a big square, 2 by 2. Break it up into 1 by 1 squares as I have done. Soooo the big square has area of 4. You'll notice that the area of the circle is less than that of the squares, it ends up filling a little more than 3 of those squares. If you have a circle of Radius 1, (which is what the picture is showing), Then the area is pi.\[\large A=\pi r^2\qquad \rightarrow \qquad A=\pi \cdot 1^2\]Just something to think about :)

    Pi is a constant. It's an irrational mathematical number and it is used in math to relate two different things together. As AccessDenied has said; it creates a relationship between the circumference of a circle (That's the outside peramiter) and the diametre (that's a straight line through the centre touching the circumference) When used in radians it represents 180 degrees. When used in degrees it represents 3.1415926535897931384626433.... It keeps going and is therefore irrational.
