There are numbers which are not natural or rational numbers,
and are called transcendental numbers. These are numbers which cannot be
expressed exactly in our number system, having infinite decimals, like p and e -
with the result that we will never know what the circumference of a circle is
equal to exactly, if we have its radius. The formula is easy C (circumference)=2*p*R
(Radius).
There are two ways of trying to establish it.
