Answer 1

$so \: \: \pi \: is \: irrational$

Step-by-step explanation:

$\pi = \frac{c}{a} \: is \: a \: rational \: number \\ when \: c \: and \: d \: both \: are \: rational \: \\ numbers \\ but \: the \: c \: and \: d \: we \: calculate \: is \: \\ not \: \: exactly \: a \: rational \: number \: \\ and \: either \: c \: and \: d \: or \: both \: can \\ \\ \: be \: irrational \: number \\ since \: \frac{rational}{irrational } = irrational$

$so \: \pi \: is \: irrational \: number$
