Pi is irrational. Irrational numbers, by definition, have no factors.
its pi and its 3.14
you see pi is easy as pie all you have to do is remember 3.14159265
in terms of pi- when using the symbol for pi instead of 3.14 or 22/7 in the end result of an equation
area = pi * radius* 2
because of the simplicity of its definition
By definition Pi is the relation between the radius and circumference of a circle.
Easy As Pi
I assume that you mean "the 'definition' of pi", which is the circumference of a circle divided by it's diameter (c/d).
Definition: Pi is a number - approximately 3.142 It is the circumference of any circle divided by its diameter.
By definition pi is the ratio between the circumference and the diameter pi=C/D so C=pi*D and C=pi*40=125.6 (if pi=3.14)
pi is defined as circumference divided by diameter circumference = pi * diameter pi is approximately 3.14159...... non-repeating, never ending decimal places
