Let's solve the problem given to us today! The problem is the following:

$\mapsto\quad\textbf{Find the circumference of a circle whose radius is 9 cm.}$

..............................................................................................................................................

We're going to find the circumference by using the formula:

$\mapsto\quad\bf{C=2\pi r}$

Substitute 9 for r:

$\mapsto\quad\bf{C=2*\pi*9}$

$\mapsto\quad\bf{C=18\pi}$

$\mapsto\quad\bf{C=28.27\:cm}$

Therefore, C = 28.27 cm.
