For almost all mathmatics and physics uses, pi is writen as 3.1417. But it is actually an irrational number, and has no perfect answer.
Pi is an irrational number, meaning it never ends.
we can find rational numbers how much nearer to pi by constructing a number which has large repeating block as pi
Because they exist just as much as other numbers.
there are infinite numbers in pi
Pi belongs to the sets of real numbers, transcendental numbers and irrational numbers.
There is no end to the digits of pi since pi is an irrational number it goes on forever and there is no end to it, so yes, there are much more than 2.5 trillion digits of pi
The first numbers of pi is 3.14159265358979323846264338327950288419716939937510 58209749445923078164062862089986280348253421170679
Pi= 3.14159265
'pi' is IRRATIONAL. This means that it cannot be converted to a ratio/fraction/quotient. pi = 3.141592.... (the '....' means that the decimal recurs to infinity). When given pi = 3.14 or 3.1416, or 22/7 these are only approximate values and NOT the true value, which remains unknown. Rational No. is 2.123123123..... Because the digits are in a regular order of '123'. so can be converted to a ration/fraction. Irrational No's ; Square roots of prime numbers.
The first twelve numbers of pi are 3.14159265358
'pi' was known before Pythagoras. The Sumerian Civilisation found the constant of proportion between a circles diameter and circumference to be 3.141592..... Later, the Classical Greeks (Pythagoras) gave this 'constant of Proportion' the name 'pi' . 'pi' in the classical Greek alphabet is the lower/small case letter 'p', for Proportion. There it has stayed ever since. Algebrqaically Circumference is directly proportional to diameter. C directly proportional d Equating C = kd 'k' is constant of proportion and as mentioned above given the symbol 'pi' Hence C = pi*d pi = C/d or pi = C / 2r NB ; d = 2r Hence the modern equ'n C = 2pir
