The formula for calculating the cricumference of a circle is:


C=2\pi r

Given that:


\begin{gathered} \pi=3.14 \\ r=18ft \end{gathered}

We substitute the values into the formula, as solve as follows:


\begin{gathered} C=2\pi r \\ \Rightarrow C=2*3.14*18\text{ =113.04} \\ \Rightarrow C=113.04ft \end{gathered}

Thus, the circumference of the circle is 113.04ft
