Today I learned about pi and how it was created. In this blog I will summarize the number pi or 3.14 to you viewers and my one follower. The number pi is used to find the circumference of a circle. Diameter times  pi equals circumference. First the Babylonians found that pi was roughly around 3. Then Archimedes found that  pi was around 22/7. Also in 1706 the symbol for pi was created and  was later  proved that pi was an irrational number. Many people and machines have searched and are still searching for the end of the number pi. In 2002 pi was converted to decimal places to 1,241,100,000,000. That is enough to to take you 62 laps around the world.
