How do find the value of pi?

Answer 1

To only three significant digits, pi is equal to 3.14. As for the method of finding pi, there are a few. Geometrically, pi can be obtained by finding the area of inscribed polygons with many sides. This can be written as an infinite series where the sides of the polygons increase unto infinity when it finally becomes the circle. In this case, the area of the circle with a radius of 1 is equal to pi. On the other hand, one can do the same thing with perimeters, then dividing the perimeter by the diamter. This will also give you pi. This was Archimedes' method, the previous was a method used by earlier mathematicians. In summation, the value of pi can be seen as the area of a circle with radius 1 or the ratio of the circumference to the diameter.
