The number π is a mathematical constant that is the ratio of a circle’s circumference to its diameter. Being an irrational number, π cannot be expressed exactly as a ratio of any two integers (fractions such as 22/7 are commonly used to approximate π but no fraction can be its exact value). Consequently, its decimal representation never ends and never settles into a permanent repeating pattern. The digits appear to be randomly distributed. ( more on en.wikipedia.org/wiki/Pi )
Something is infinite if, taking it quantity by quantity, we can always take something outside.
