Hoje comemora-se em todo o mundo o dia do Pi, por isso vamos a uma lição de história!! Today marks throughout the world the day of Pi, so we are going to a lesson in history!

A história do cálculo de π tem registos desde a Babilônia (1800 aC) que consideravam o valor 3 como uma boa aproximação. The history of the calculation of π has records from Babylon (1800 BC) believed that the value 3 as a good approximation. Em 1700 aC, matemáticos no Egito antigo descobriram que a razão entre o comprimento de uma circunferência e seu diâmetro é a mesma para qualquer circunferência. In 1700 BC, mathematicians in ancient Egypt discovered that the ratio between the length of a circle and its diameter is the same for any circle. Eles definiram o que chamamos hoje de π como um número “um pouco maior que 3″, chegando a aproximação de que um círculo de diâmetro 9 unidades tem a mesma área de um quadrado cujo lado tem 8 unidades ( π = 3,1228 ), com um erro inferior a 1%. They define what we call today a number of π as "slightly more than 3", reaching the nearest to a circle diameter of 9 units have the same area of a square with sides have 8 units (π = 3.1228), with an error less than 1%. Ainda no Egito, o papiro de Ahmes, (cerca de 1600 aC) dá o valor 3,16 para a constante π . Even in Egypt, the papyrus of Ahmes, (about 1600 BC) gives the value 3.16 for the constant π.

O número π também foi calculado por várias outras civilizações antigas, sendo conhecidos os estudos de Arquimedes (287/212 aC), Tsu Chung-Chi (430/501 dC). The number π was also calculated by a number of other ancient civilizations and are known studies of Archimedes (287/212 BC), Tsu-Chung Chi (430/501 AD). Chineses, Hindus e árabes também realizaram cálculos importantes para a determinação de uma aproximação de π na antiguidade. Chinese, Indians and Arabs also made calculations important for determining an approximation of π on seniority.

Matematicamente falando, se considerarmos c como o comprimento de uma circunferência ed como o diâmetro, temos o seguinte cálculo: Mathematically speaking, if we consider c as the length of a circle to the diameter d, we have the following calculation:
