# PAI KA MAN 22/7 KYO HOTA HAI

pi = circumference / diameter which is very close to 22/7

therefore we take the value of pi as 22/7

pi is not actually equal to 22/7. It is a irrational no. with a value of 3.14159265358979 upto 15 digits. Evaluate 22/7 upto 15 digits and see the difference in their values. pi is taken to be approx. 22/7 for calculative convience.

3.14 is the value of 22/7

Because circumference/diameter =62823/20000=3.1416 or 22/7

Circumference of circle = 2?r

And,

?=Circumference of circle/2r

By using heat and trial method ,let any value of radius and put on this formula ...... We will get that ?=22/7 or 3.14

Pi is ratio of circumfrence and diameter of a circle. But always we cannot get same value of it.it is irrational number .

Succinctly, pi?which is written as the Greek letter for p, or ??is the ratio of the circumference of any circle to the diameter of that circle. 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.) Hence, it is useful to have shorthand for this ratio of circumference to diameter. According to Petr Beckmann's?A History of Pi, the Greek letter ? was first used for this purpose by William Jones in 1706, probably as an abbreviation of periphery, and became standard mathematical notation roughly 30 years later.

Try a brief experiment: Using a compass, draw a circle. Take one piece of string and place it on top of the circle, exactly once around. Now straighten out the string; its length is called the circumference of the circle. Measure the circumference with a ruler. Next, measure the diameter of the circle, which is the length from any point on the circle straight through its center to another point on the opposite side. (The diameter is twice the radius, the length from any point on the circle to its center.) If you divide the circumference of the circle by the diameter, you will get approximately 3.14?no matter what size circle you drew! A larger circle will have a larger circumference and a larger radius, but the ratio will always be the same. If you could measure and divide perfectly, you would get 3.141592653589793238..., or pi.

Otherwise said, if you cut several pieces of string equal in length to the diameter, you will need a little more than three of them to cover the circumference of the circle.

Pi is most commonly used in certain computations regarding circles. Pi not only relates circumference and diameter. Amazingly, it also connects the diameter or radius of a circle with the area of that circle by the formula: the area is equal to pi times the radius squared. Additionally, pi shows up often unexpectedly in many mathematical situations. For example, the sum of the infinite series

1 + 1/4 + 1/9 + 1/16 + 1/25 + ... + 1/n2 + ... is ?

2

/6

The importance of pi has been recognized for at least 4,000 years.?A History of Pi?notes that by 2000 B.C., "the Babylonians and the Egyptians (at least) were aware of the existence and significance of the constant ?," recognizing that every circle has the same ratio of circumference to diameter. Both the Babylonians and Egyptians had rough numerical approximations to the value of pi, and later mathematicians in ancient Greece, particularly Archimedes, improved on those approximations. By the start of the 20th century, about 500 digits of pi were known. With computation advances, thanks to computers, we now know more than the first six billion digits of pi.

3.14......... Ko fraction melao beta????????????

It is calculated by a great mathematician

Because pi is the actual ratio of circumference to the diameter of circle. Value is irrational. This value is approximation. It is not exact value.

Agar ham kisi bhi circle ke uske paridhi ko uske vyas se use divide karte h to vo22/7 ke lagbhag aata h Isi liye pai ka maan 22/7 hota h

pi is an irrational number it is actully 3.14...nd so on. never ending we?generally?use pi as 22/7?because it gives us a very approx value that is 3.14?but for the sake of calculations we take it as 22/7
