[tex]\begin{gathered} C=2\text{ }\pi\cdot radius \\ C=94.24\text{ ft} \end{gathered}[/tex]
Explanation
the circumference of a circle is given by:
[tex]C=2\text{ }\pi\cdot radius[/tex]
then Let
radius=15 ft
replace
[tex]\begin{gathered} C=2\text{ }\pi\cdot radius \\ C=2\text{ }\pi\cdot15\text{ ft} \\ C=94.24\text{ ft} \end{gathered}[/tex]
I hope this helps you
