The formula to calculate the circumference (C) of a circle is,
[tex]C=\pi D[/tex]
Given:
[tex]\begin{gathered} D=\text{Diameter}=23ft \\ \pi=3.14 \end{gathered}[/tex]
Therefore,
[tex]\begin{gathered} C=3.14\times23ft=72.22ft \\ \therefore C=72.22ft \end{gathered}[/tex]
Hence, the circumference is about 72.22ft.
