The formula for calculating the cricumference of a circle is:
[tex]C=2\pi r[/tex]
Given that:
[tex]\begin{gathered} \pi=3.14 \\ r=18ft \end{gathered}[/tex]
We substitute the values into the formula, as solve as follows:
[tex]\begin{gathered} C=2\pi r \\ \Rightarrow C=2\times3.14\times18\text{ =113.04} \\ \Rightarrow C=113.04ft \end{gathered}[/tex]
Thus, the circumference of the circle is 113.04ft
