This is the wiki of "Approximations of π"Recall, π is defined as the ratio of the circumference (say c) of a circle to its diameter (say d) That is, π=c/d This seems to contradict the fact that π is irrational7 (The latter value, also written as 22/7, is one many people remember from school as "the" value of π) In modern, decimal terms, these values are correct to two decimal digits 310 71 =and31 7 = Archimedes's method is based on polygonal approximations to the circle The basic idea is to repeatedly double the

Both the values are the approximate values of π ( pi) If you remember pi is an irrational number and no irrational number can be represented in form of p/q where q not equal to 0 Also an irrational number has non repeating and non terminatingThe Chinese mathematician Zu Chongzhi, around 480 AD, calculated that < π < and suggested the approximations π ≈ 355 / 113 = and π ≈ 22 / 7 = , which he termed the Milü (''close ratio") and Yuelü ("approximate ratio"), respectively, using Liu Hui's algorithm applied (It is also a transcendental number) Therefore there is no question of either Archimedes or Aryabhatta finding the exact value of Pi What we have down the timeline is a better and better approximation to Pi The best approximation to Pi that I know is its calculation to 124 trillion decimal places using a supercomputer
Pi Day Invention, History and Interesting Facts Pi day is observed on 14 March annually and also on this date Albert Einstein was born Recall, π is defined as the ratio of the circumference (say c) of a circle to its diameter (say d) That is, π=c/d This seems to contradict the fact that PI has now been calculated to 124 trillion places Most people use 3142 for decimal calculations, or 22/7 (3 and one seventh) as a vulgar or simple fraction 22/7 = but PI actually starts Now 355/113 = 3,
Spelled out as "pi") is a mathematical constant It is defined in Euclidean geometry as the ratio of a circle's circumference to its diameter, and it also has various equivalent definitions It appears in many formulas in all areas of mathematics and physics It is approximately equal to 8 Around 150 years later in 02, a Japanese scientist decided to give calculating π a try using the super computer, Hitachi SR 8000 While Ceulen and Shanks were both limited to calculating their digits by hand, using Hitachi, the first 124 trillion decimal places of π were able to be calculated 9Then recite as many digits as you can in 30 seconds for our Pi Day Competition!!
