- 6. Pi denotes the ratio of the circumference of a circle to its diameter. It is an irrational number, meaning that it cannot be expressed as a ratio of two integers. Approximation of pi began in the second millennium BC. No single mathematical subject can trace its history as far back as pi. The ancient Babylonians calculated the area of a circle by taking three times the square of its radius, which gave a value of pi as 3. One Babylonian tablet, which dates back to approximately 1900-1680 BC, indicates a value of 3.125 for pi. The ancient Egyptians also used measurement to give pi the approximate value of 3.1605 around 1650 BC. The first calculation of pi came around 287- 212 BC and was done by Archimedes of Syracuse. He approximated the area of a circle by using the Pythagorean Theorem to find the area of two regular polygons, one inscribed within the circle and one in which the circle was circumscribed. He knew that the area of the circle lied between these two values, so he showed that pi was between 31/7 and 310/71. Mathematicians first began using the Greek letter π in the 1700s when it was introduced by William Jones. The use of the symbol later became popularized by Leonhard Euler, who adopted it in 1737. Even today mathematicians continue to seek more accurate approximations of pi, largely however, only to break records. They have discovered new approaches that, when combined with great computational power, extended the decimal representation of pi to over 10 trillion digits.
