Answer:

r = 6.2ft, C = 38.96ft

Explanation:

Given the value for the diameter d = 12.4ft

To get the radius;

[tex]\begin{gathered} \text{radius =}\frac{diamater}{2} \\ r=\frac{d}{2} \\ r=\frac{12.4}{2} \\ r=6.2ft \end{gathered}[/tex]

Get the circumference;

[tex]\begin{gathered} C=\pi d \\ C=3.14\cdot12.4 \\ C=38.96ft \end{gathered}[/tex]

Hence the radius is 6.2ft and the circumference is 38.96ft
