Explanation:
The formula of the circumference of a circle is:
[tex]C=2\pi r[/tex]We have C = 25.12 ft and we have to use 3.14 for pi. Replacing and solving for r:
[tex]\begin{gathered} 25.12=2\cdot3.14\cdot r \\ r=\frac{25.12}{2\cdot3.14} \\ r=\frac{25.12}{6.28} \\ r=4 \end{gathered}[/tex]Answer:
r = 4 feet
