Answer:

circumference - diameter

circumference - 2 times radius

area - radius squared

Explanation:

we know that

The circumference of a circle is equal to

$C=\pi D$ or
$C=2\pi r$

where

D is the diameter and r is the radius

therefore

$\pi =(C)/(D)$ or
$\pi =(C)/(2r)$

The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius

The area of the circle is equal to

$A=\pi r^(2)$

therefore

$\pi =(A)/(r^(2) )$

The number pi is the ratio Area - radius squared
