 # How Did Archimedes Calculate Pi?

## Does the number pi end?

Pi is an irrational number.

As such, it has no final digit.

Furthermore, there is no pattern to its digits..

## What if PI was 3?

If Pi was equal to 3, it wouldn’t exist. We wouldn’t call it Pi, because it’s simply 3. By the way, maybe we would be able to design round squares in such a world.

## What is the difference between 22 7 and pi?

22/7 is a rational approximation to pi, just as 3.14 is. That is, both 22/7 and 3.14 are rational numbers (fraction and terminating decimal, respectively) that are close enough to the exact value of pi for elementary work. 22/7 is a rational number, namely 3.1428571428571428571428571428571…

## Who is the father of maths?

ArchimedesArchimedes is known as the Father Of Mathematics.

## Why is the number 1729 special?

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 also the sum of the cubes of 12 and 1- cube of 12 is 1728 and cube of 1 is 1; adding the two results in 1729.

## What Ramanujan invented?

Indian mathematician Srinivasa Ramanujan made contributions to the theory of numbers, including pioneering discoveries of the properties of the partition function. His papers were published in English and European journals, and in 1918 he was elected to the Royal Society of London.

## How was Pi originally calculated?

Here’s a brief history of finding π. The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. … The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.

## Why is Pi 22 divided 7?

The pi value in fraction is 22/7. It is known that pi is an irrational number which means that the digits after the decimal point are never-ending and being a non-terminating value. Therefore, 22/7 is used for everyday calculations. ‘π’ is not equal to the ratio of any two number, which makes it an irrational number.

## How did Ramanujan calculated pi?

Calculates circular constant Pi using the Ramanujan-type formula. The calculation ends when two consecutive results are the same. The accuracy of π improves by increasing the number of digits for calculation. In 1914, the Indian mathematician Ramanujan discovered the formula for computing Pi that converges rapidly.

## Why is 3.14 called pi?

It was not until the 18th century — about two millennia after the significance of the number 3.14 was first calculated by Archimedes — that the name “pi” was first used to denote the number. … “He used it because the Greek letter Pi corresponds with the letter ‘P’… and pi is about the perimeter of the circle.”
