MATHEMATICAL PI
There are many fascinating numbers in mathematics. One of the most interesting number relationships that students can discover in geometry is that the ratio of the circumferenceof a circle (the distance around a circle) to the diameter of a circle (the length of a line across a circle that passes through its center) is approximately equal to 3.14 or . This ratio is true for all circles. It is called pi, and is represented by the Greek letter .
