In the computer age, pi has been estimated to its two-quadrillionth digit. Later mathematicians extended the number of decimal places in this irrational number through rigorous calculations. In 1706, William Jones was the first to introduce a Greek letter for pi, which was later adopted by the mathematician Euler to represent the ratio between a circle’s circumference to its area. Antiphon and Bryson of Heraclea came up with the innovative idea of. A general estimate for pi is 22/7 or 3.14. When the Greeks took up the problem, they took two revolutionary steps to find pi. However, it was the Greek mathematician Archimedes that calculated pi to be between 223/71 and 22/7. In mathematics, the ratio between a circle’s circumference and diameter is given as pi. Babylonians estimated pi as 3.125, and the Egyptians approximated pi to be 3.1605. Some mathematical problems that feature pi are the area of a circle, a circle’s circumference, arc length and the different surface area and volume formulas for a cone, sphere and cylinder. The history of pi dates back to the ancient Babylonians and Egyptians. For example, the area of a sphere is 4 x pi x radius squared, and its volume formula is 4/3 x pi x radius cubed. number and it is very important to solve many mathematical equations. Similarly, many of the area and volume formulas for different geometric solids were formulated with pi as a term in them. Mathematics is also not about remembering complex rules to solve problems in the. While the circle’s circumference is given by the formula 2 x radius x pi, its area formula is pi x radius squared.
