  2. Pi Day - Wikipedia

    en.wikipedia.org/wiki/Pi_Day

    Pi Approximation Day is observed on July 22 (22/7 in the day/month date format), since the fraction 22 ⁄ 7 is a common approximation of π, which is accurate to two decimal places and dates from Archimedes. [33] In Indonesia, a country that uses the DD/MM/YYYY date format, some people celebrate Pi Day every July 22. [34] Tau Day, also known ...

  3. Proof that 22/7 exceeds π - Wikipedia

    en.wikipedia.org/wiki/Proof_that_22/7_exceeds_π

    Archimedes wrote the first known proof that ⁠ 22 / 7 ⁠ is an overestimate in the 3rd century BCE, although he may not have been the first to use that approximation. His proof proceeds by showing that ⁠ 22 / 7 ⁠ is greater than the ratio of the perimeter of a regular polygon with 96 sides to the diameter of a circle it circumscribes.

    Archimedes computed upper and lower bounds of π by drawing a regular hexagon inside and outside a circle, and successively doubling the number of sides until he reached a 96-sided regular polygon. By calculating the perimeters of these polygons, he proved that ⁠ 223 / 71 ⁠ < π < ⁠ 22 / 7 ⁠ (that is, 3.1408 < π < 3.1429 ). [ 50 ]
