The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
Ancient Greek mathematician Archimedes of Syracuse, who lived in the third century B.C. and is considered the greatest mathematician of the ancient world, is credited with doing the first calculation of pi.
And how did it get the name "pi"? It was first called "pi" in 1706 by [the Welsh mathematician] William Jones, because pi is the first letter in the Greek word perimitros, which means "perimeter."
What did Aryabhata discover? Aryabhata discovered an approximation of pi, 62832/20000 = 3.1416.
The first rigorous approach to finding the true value of pi was based on geometrical approximations. Around 250 B.C., the Greek mathematician Archimedes drew polygons both around the outside and within the interior of circles. Measuring the perimeters of those gave upper and lower bounds of the range containing pi.
Albert Einstein did not invent pi. Pi describes the ratio of the circumference of a circle to its diameter and was discovered in ancient times.
It is known that \pi is an irrational number and therefore cannot be expressed as a common fraction. Its value is approximately equal to 3.141592. Since Archimedes was one of the first persons to suggest a rational approximation of 22/7 for \pi, it is sometimes referred to as Archimedes' constant.
The value of pi is approximately 3.14, or 22/7. To 39 decimal places, pi is 3.141592653589793238462643383279502884197. Pi is an irrational number, which means it is not equal to the ratio of any two whole numbers. Its digits do not repeat.

1729, the Hardy-Ramanujan Number, is the smallest number which can be expressed as the sum of two different cubes in two different ways. 1729 is the sum of the cubes of 10 and 9 - cube of 10 is 1000 and cube of 9 is 729; adding the two numbers results in 1729.
While treating pi as equal to 3.14 is often good enough, the number really continues on forever, a seemingly random series of digits ambling infinitely outward and obeying no discernible pattern — 3.14159265358979….
The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
We have known since the 18th century that we will never be able to calculate all the digits of pi because it is an irrational number, one that continues forever without any repeating pattern.
Regardless of the circle's size, this ratio will always equal pi. In decimal form, the value of pi is approximately 3.14. But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666...). (To only 18 decimal places, pi is 3.141592653589793238.)
Not much. NASA only uses around 15 digits of pi in its calculations for sending rockets into space. To get an atom-precise measurement of the universe, you would only need around 40. So computing trillions of digits of pi is mostly about showing off computer power.
The first recorded use of π as a mathematical symbol comes from the Welsh mathematician William Jones in a 1706 work called Synopsis Palmariorum Matheseos, in which he abbreviated the Greek περιϕέρεια, (meaning “circumference,” or “periphery”) to its first letter: π.
The first 10 digits of pi (π) are 3.1415926535
Why not calculate the circumference of a circle using pi here. Or simply learn about pi here. Maximize the fun you can have this Pi Day by checking out our Pi Day Merch. 3.
The string 123456789 did not occur in the first 200000000 digits of pi after position 0. (Sorry! Don't give up, Pi contains lots of other cool strings.)
That's because pi is what mathematicians call an "infinite decimal" — after the decimal point, the digits go on forever and ever. Students are usually introduced to the number pi as having an approximate value of 3.14 or 3.14159.
The last 100 digits of the 100 trillion pi it discovered are: 4658718895 1242883556 4671544483 9873493812 1206904813 2656719174 5255431487 2142102057 7077336434 3095295560.
Pi Day is celebrated around the world every year on March 14 (3/14, or simply 314) because 314 constitutes the first three digits of number pi.
One fun way to memorize the first few digits is to use sentence mnemonics for pi— phrases in which the number of letters of each successive word corresponds to a digit of pi. Here are some well-known pi mnemonics: “Wow! I made a great discovery!” (3.14159…)
Since it is defined mathematically as the ratio of circumference of circle by diameter,it is used in the every equation of circle. also circle has no sides so that no other equation can be used.
Albert Einstein likely never took an IQ test but is estimated to have a 160 IQ—but even that can't stand up to these masterminds.
Zu Chongzhi, a Chinese mathematician and astronomer from the 5th century, had made a remarkable achievement by determining the Pi value with an accuracy of seven decimal places, between 3.1415926 and 3.1415927. His calculation remained the world's most accurate for nearly 1,000 years until the 14th century.
