Step-by-step explanation:

The formula of the circumference of a circle is:

$C=2\pi r$

We have C = 25.12 ft and we have to use 3.14 for pi. Replacing and solving for r:

$\begin{gathered} 25.12=2\cdot3.14\cdot r \\ r=(25.12)/(2\cdot3.14) \\ r=(25.12)/(6.28) \\ r=4 \end{gathered}$

Answer:

r = 4 feet
