We are required to calculate the circumference of the circle

`\begin{gathered} The\text{ circumference of a circle can be calculated by the formula} \\ C=2\pi r \\ Where\text{ r = radius of the circle} \end{gathered}`
`\begin{gathered} For\text{ this question, r = 6ft} \\ Thus,\text{ C=2 x }\pi\text{ x 6 = 37.699 ft} \\ C=37.7ft\text{ \lparen nearest tenth\rparen} \end{gathered}`

The circumference of the circle is 37.7 ft (nearest tenth)
