The circumference of a circle is given by the formula

$\text{circumference = 2}\pi\text{ r}$

Where r is the radius and pi is a constant.

The radius of the circle is given to be 18cm

We will then have to substitute the value of r = 18 and pi = 3.14

$\begin{gathered} \text{circumference = 2 x }\pi\text{ x r} \\ \Rightarrow\text{ 2 x 3.14 x 18} \end{gathered}$

Circumference of the circle is = 113.04 cm
