Summary

[edit]
Description
English: A square with inscribed circle and subdivided into parts by a grid, illustrating an ancient method of calculating a circular area by approximation. As demonstrated in the Rhind Papyrus (book II, problem 48) copied by Ahmes/Ahmose around 1550 BC. The area of a circle is estimated as roughly 7/9 of a square whose side equals the circle's diameter (i.e. pi is approximated by 28/9 = 3.111..).
Deutsch: Ein Kreis, der einem Quadrat eingeschrieben ist, das dreiteilend durch ein Gitter zerlegt wird. Zur Illustration der näherungsweisen Berechnung einer Kreisfläche nach der im Papyrus Rhind überlieferten Methode, als Kopie durch Ahmes/Ahmose etwa 1550 v.Chr. Die Fläche eines Kreises wird damit auf ungefähr 7/9 der eines Quadrats geschätzt, dessen Seitenlänge gleich dem Kreisdurchmesser ist; die Zahl pi wird hierbei angenähert durch 28/9 = 3.111..).
