**The Amazing Factors About the Mathematical Constant "π"**

Hi friends i think all of us know that there is a mathematical constant we are using for various calculation in mathematics named **PI** .we denote it as a symbol **"π"**.Do you know some history about PI.There was two mathematicians who spend their major portion of their time for the study of this constant.they were great Archimedes and **Ludolph van Ceulen**. so this constant also known as **Archimedes's constant** and **Ludolphine's digit**.

Actualy **Pi** is a ratio between its Perimeter to its diameter **π=P/D** P is perimeter of circle and D is diameter of circle.its value found as 22/7 or 3.14. Indian ancient scientist Aryabatta also made major studies on **Pi**.in his ancient book Aryabadeeyam he mentioned that **π=63832/2000**.He said if a circle is having its diameter 2000 then it will have perimeter of 63832.this value he got from his repeated studies.

The ancient Indian scientist Bhaskaracharya found that **π=22/7**.He found for accurate perimeter multiply diameter with **3927/1250.ie P=Dx3927/1250**.

It is impossible to find out the exact value of **Pi**.The above mentioned scientists also couldn't find out it.**Pi** is an irrational number.Till today scientist found around 10 trillion numbers after its decimal point.The last ten latest numbers are **0191295669**.it is impossible to find out the complete value for **Pi**.

To remember the approximate value of **Pi** remember this**"MAY(3) I(1) HAVE(4) A(1) LARGE CONTAINER(9) OF(2) COFFEE(6**).Just check out the respective number of each word in this sentence.you can also use this sentence **HOW(3) I(1) WISH(4) I(1) COULD(5) RECOLLECT(9) OF(2) CIRCLE(6) THE(3) EXACT(5) RELATION(8) ARCHEMEDE(9) UNWOUND(7)**

It is also interesting that every year we are celebrating **Pi** day it is 14thof March .ie **month-date **it will be 3-14.ie similar as the value as 3.14.

hope all of you understood what i am trying to express .thanks
