Because it's irrational. It goes on forever, the reason for this is that Pi is used to work out the circumference of a circle.
Circles don't have sides, so you can't times one by another to get the Area.
You have to use a number that goes on forever, because technically, a circle goes on forever.
Mathematicians wanted a number to work out circles. And after much calculation, they finally discovered an irrational number, Pi.
3.142. It cannot be turned into a fraction.

Is 10x 3.14 irrational?
The product of two rational numbers, as in this example, is always RATIONAL.However, if you mean 10 x pi, pi is irrational; the product of a rational and an irrational number is ALWAYS IRRATIONAL, except for the special case in which the rational number is zero.
What is the nearest whatever of Pi?
pi = 3.1415926535897932384626433832795... pi to the tenths = 3.1 pi to the hundredths = 3.14 pi to the thousandths = 3.142 pi to the ten-thousandths = 3.1416 pi to the 10th decimal places = 3.1415926536 etc. ============================
What is the diameter if the circumferance is 56 inches?
Just divide 56 by pi. Pi is approximate 3.14; or use the "pi" key on your scientific calculator.Just divide 56 by pi.

What is the formula for circumference in terms of pi?
d * pi or 2 * r * pi Where d is diameter and r is radius and pi = 3.14159
A paricle moves along a circular path of radius r and completes a half circle calulate the distance traveled by the particle and the dispalcement of the particle?
distance = 1/2 circumference displacement = 2 r (special case because exactly half of the circle was travelled) circumference = 2*pi*r 1/2 circumference = 1/2*2*pi*r = pi * r
Why is pi 3.14 a special number?
pi is irrational.
What is the final digit in Pi?
Pi never ends. That's why it's so special.
What is mathematically special about March 14?
It is PI day
Why is pi day 2015 so special?
The date can be written as 3.14.15 which are the first digits of pi. That can only happen once every hundred years.
What is the circumference of a circle with a diameter of 1 inch?
You need the formula circumference = pi x diameter pi = 3.14.. This is by the way the definition of the special number pi.
What is the natural log of i times pi?
-1 it's a special equation
The special number that relates the diameter of a circle to its circumference is?
Pi (3.14159265358.....)
Is the square of pi a rational?
No. Pi is a special kind of irrational number called a transcendental number. This means that no power of pi (other than 0), or any combinations of its powers is rational.
What is special about pi and what you have to use it for?
Pi is an irrational number, and is the circumference of the unit circle. It's a neat number to use in all sorts of circumstances.
If a circle has the diameter of 3 what is the cirumference?
The circumference is equal to the diameters times pi. Pi is approximately 3.14, so just multiply 3 x 3.14. If you have a scientific calculator, it will probably include a special key to give you a better approximation for pi.The circumference is equal to the diameters times pi.

Does 5 times pi end?
No.You can do just about anything to pi, and the answer will still be a transcendental number (a special kind of irrational number than can't be the solution of an algebraic equation).The only thing I can think of is pi/pi =1 (or multiples of this).
What is special about the number pi?
It's the ratio between the circumference of any circle to its diameter.
