To find the circumference of a circle, you can use the formula:
\[
C = 2 \pi r
\]
where \( C \) is the circumference and \( r \) is the radius.
Given that the radius \( r = 4.7 \) ft:
\[
C = 2 \pi (4.7)
\]
Calculating this:
\[
C \approx 2 \times 3.14159 \times 4.7 \approx 29.5 \text{ ft}
\]
So, the circumference of the circle, rounded to the nearest tenth, is:
\[
\boxed{29.5} \text{ ft}
\]

C = 2 \pi r
