Although many sought to find it, the calculation of pi, which is also expressed by the fraction 22/7, is commonly credited to Greek mathematician Archimedes of Syracuse more than 2,200 years ago.

Archimedes' method of approximating π with polygons, and similar techniques developed in China and India, would be the dominant way mathematicians would approach the calculation of the digits π ...

Archimedes' method finds an approximation of pi by determining the length of the perimeter of a polygon inscribed within a circle (which is less than the circumference of the circle) and the ...

Archimedes' value, however, was not only more accurate, it was the first theoretical, rather than measured, calculation of pi. How did he do it?

This final estimate gave a range for π between 3.1408 and 3.1428, which is accurate to two places. Archimedes' method of approximating π with polygons, and similar techniques developed in China and ...

Greek mathematician Archimedes of Syracuse calculated the infinite mathematical concept pi in the 200s BCE, which we celebrate annually on March 14, or Pi Day.

An algorithm to calculate Pi on IBM’s quantum computers honors Pi Day—and helps us understand how a quantum computer works.

Then it multiplies stride length times the number of steps to calculate how far you walked. Archimedes used a similar method to estimate the circumference of a circle, and so to estimate pi.
