       The Pi concept was created by the Greeks. The pie is used to get the circumference of a circle. In Greece pi is actually a letter. It is equal to 3.14159. Pi is an irrational number. That as a number it does not stop. It can also be used as a fraction. The fraction form is 22/7. Yet nobody knows what led the Greeks to create such a long number. This concept is sometimes used in Geometry or Trigonometry.The Greeks made Pi  about more than 1,000 years ago.
        Some of the Great Pyramids were created with the knowledge of Pi. Pi is also C/D. That means it is the circumference over the diameter. Pi now is used for many things. This concept is used by engineers,architects, and mathematicians. Pi has been used for many things today, but it is it still a mystery to everyone why the Greeks used the numbers they did and their patterns. I think that Pi is a very important concept to all of us, because it has helped us learn about history and mathematics.
