Pi has more than a million digits to it. Its 3.14159...etc
You don't: it simply is. Irrational refers to the fact that pi cannot be exactly defined using a decimal system. Pi is not 3.14, it is in fact 3.141592653589793238462643383279502884197169399375105820974944592307816406286208998628034825342117067982148086513282306647093844609550582231725359408128481117450284102701938521105559644622948954930381964428810975665933446128475648233786783165271201909145648566923460348610454326648213393607260249141273724587006606315588174881520920962829254091715364367892590360011330530548820466521384146951941511609... The fact that this number goes on and on means it is irrational
No. the symbol for pi stems off of the Greek letter pi, probably due to the fact that the discoverer of pi was Greek.
Pi * * * * * No it is not. Apart from the fact that pi is an irrational number and so its decimal representation is infinitely long, pi is approximately 3.14159 - not quite the same as 3.149!
Nobody because its a natural fact that the circumference of a circle divided by its diameter is always equal to pi.
It was a cool looking greek letter.

he is cool.
it is cool
pi is an irrational number because it cannot be expressed as a ratio of two integers. In fact, it is a transcendental number, but that is not relevant here. 3.14 is a rational approximation to pi. It is not equal to pi.
Pi does in fact equal 3.14159.
It was found by the fact that for any circle when its circumference is divided by its diameter the quotient is always the value of pi which is an irrational number.
