WebMar 14, 2024 · There are many ways pi can be approximated that you can try yourself. One of the most well-known methods is Archimedes Polygon Approximation. This method works by inscribing a polygon within a circle and circumscribing another outside the circle, and determining the perimeters of the polygons. WebPolygon Approximation Era. The first recorded algorithm for rigorously calculating the value of π was a geometrical approach using polygons, devised around 250 BC by the Greek mathematician Archimedes. This polygonal algorithm dominated for over 1,000 years, and as a result π is sometimes referred to as "Archimedes' constant". on schuhe firma
