History of Pi

Reading Comprehension for March 14

To find the area of a circle, you multiply pi times the radius of the circle squared. To find the circumference of a circle, you multiply pi times the circle's diameter. Pi is a useful number, but before we could use it, someone had to figure out that there was such a thing as pi.

Pi is the ratio of the circumference to the diameter of a circle. It is the same number for every circle. The digits for the number pi begin 3.1415926535 and continue without ever ending or repeating. We often use a shorter estimation for pi, such as 3.14.

In ancient times, people in China, Babylon, and Egypt used pi. Even the Bible mentions circle calculations that are based on the number pi. In those times people were not using decimals yet, so they used either the whole number 3 or fractions for pi.
