# How many digits are in pi?

Pi has infinitely many digits. Actually, Pi is an irrational number, which means it cannot be written as a fraction But researchers in Japan say they have surpassed that… mark by a boatload: over a TRILLION digits. The "Pi Computer Project" (or PCP) finished some time in November 2010, and it calculated about 5 trillion digits! Here are just some of pi's digits, in order: 3.14159265358979323846264338327950288419 716939937510582097494459 230781640628620899862803 482534211706798214808651 328230664709384460955058 223172535940812848111745 028410270193852110555964 462294895493038196442881 097566593344612847564823 378678316527120190914564 856692346034861045432664 821339360726024914127372 458700660631558817488152 092096282925409171536436 789259036001133053054882 046652138414695194151160 943305727036575959195309 218611738193261179310511 854807446237996274956735 188575272489122793818301 194912983367336244065664 308602139494639522473719 070217986094370277053921 717629317675238467481846 766940513200056812714526 356082778577134275778960 917363717872146844090122 495343014654958537105079 227968925892354201995611 212902196086403441815981 362977477130996051870721

# Who discovered Pi?

Discovery of Pi Euclidean geometry, attributed by Greek mathematician Euclid (born 325 BC) was the first recorded system used to show Pi as a mathematical consta…nt. Pi is approximately equal to 3.14159, which is also referred to the constant circumference. William Jones used the name Pi for the Greek letter meaning the perimeter in 1706, and at a later time referred more often by Leonhard Euler. Although in 5th century Aryabhatt calculate the circumference of the earth and that time he used 22/7 as constant in the calculation. But that value was not assigned to any character, as Euclid did. An Overview of Pi History The history of the pi is usually divided into three eras. The ancient period was the time it was studied in geometric terms. The classic era took place in 17th Europe following the invention of calculus. The current one is the digital period, where computers are used to analyze and compute the data. The Susa math tablets (c 2000 BC) can shed light on some facts about pi. These were set down in cuneiform and discovered in Shush, Iran. There it is said that the ratio of the circumference of a circle compared to a hexagonal perimeter is 1:0.96. This is taken by some experts as a pi=3.125. Most of the ancient civilizations located an area by multiplying a square of the circumference by 1/12. The Ahmes Papyrus While no Egyptian texts state their use of pi, some math experts suggest otherwise. The Ahmes papyrus (or Rind papyrus) seem to indicate some awareness on their part. It was composed around 1820 BC. It is mostly concerned with problems about locating the circle's area from the diameter. When studying the facts about pi, it is about multiplying the diameter by 8/9. This is the p/4. From the text in the papyrus, the value is at least p= (256/81) =3.1605. The Moscow Papyrus There is another Egyptian papyrus called the Moscow papyrus (where it is kept). It deals with mathematical problems. One problem is about a basket area 4 times the diameter square times 8/9 square. Some experts have determined that it is an open ended semi-cylinder. In terms of pi, the error is only a small value. The answer is still correct even if the shape is hemispherical. The Greeks The Greek mathematician Archimedes (250 BC) knew some facts about pi. He stated that two ratios (area to radius squared and circumference to diameter) were equal. Archimedes was not the first one to recognize it, but he was the first to show proof of it. His statement that it is between 223/71 and 22/7 are the first pi ranges used. The 22/7 is now known as the Archimedean value. The Use of the Letters Prior to the 17th century, the value was never expressed in symbols. The use of the letter was first used in 1647. English math teacher William Oughtred set it down as p.d. William Jones in 1706 reduced it to just p. The Swiss mathematician Leonard Euler was the one who made usage of p popular. Numerous symbols were used to express 3.14 but as time went on, only the p remained. The facts about pi's origin will only be known through further research. The ancient Egyptians seemed to be the first but there are still a lot of unanswered questions regarding its roots.

# How was pi discovered?

The early history of N (pi) from textual sources roughly parallels the development of mathematics as a whole. Early evidence points toward use of an approximation for the len…gth of 'circumference' with respect to its 'radius' (~ 3 1/7) in the designs of the pyramids in Egypt. The Great Pyramid (2500 BC) was built with a perimeter of 1760 royal cubits (1 royal cubit ~ 20.64 inches or 525 mm) and a height of 280 cubits; the ratio 1760/280 ~ 2Ď€ ~ 6.29. (N ~ 3.14) Pi was discovered by the Greeks by a process called exhaustion. They observed that any polygon could be divided into triangles whose areas could be combined to get the area of the shape, so they tried the same thing with circles. They then factored in the radius of the circle, and they found pi. These triangles can theoretically get infinitely smaller, which is why pi is an irrational number.

There are 70,674 3's in the first million digits of pi. * * * * * There are 100,230 3s and 100,106 9s. Since the decimal representation of pi is essentially random, the …number of times any digit appears should be approximately 10% of the total number of digits. So, for a million digits, there should be around 100,000 of any digit so it should have been immediately apparent that the previous answer was extremely unlikely. In fact it was incorrect to a very large degree!
