kropot72 · Answer

Pi is the ratio of the circumference of a circle to its diameter. Pi is an irrational number meaning that it cannot be expressed as a fraction (an integer over an integer)

|dw:1352010348310:dw|$$\Huge{\pi = {c \over d}=3.14159}$$


100+4 multiply by 8 add to 62000 this is approximately measure of the circumfrence of the circle whose diameter is 20,000 which mathematically can be written as :-

$\Huge{62832\over20000}=3.14$
