Archimedes determined the upper and lower range of pi by finding the perimeters of inscribed and circumscribed polygons. By doubling the number of sides of the hexagon to a 12-sided polygon ...

By doubling the number of sides of the hexagon to a 12-sided polygon, then a 24-sided polygon ... (For simplicity's sake, we round off all figures to four decimal places.) Like Archimedes ...
