SOLUTION

Given the figure below;

The radius of the inscribed circle is DE;

`\begin{gathered} To\text{ determine DE;} \\ CE\text{ is divided into CD:DE}\rightarrow2:1 \\ DE=(1)/(3)* CE \\ DE=(1)/(3)*8.7 \\ DE=2.9 \\ The\text{ radius of the inscribed circle is 2.9} \end{gathered}`

The radius of the circumscribed circle is CD;

`\begin{gathered} To\text{ determine CD:} \\ CD=(2)/(3)* CE \\ CD=(2)/(3)*8.7=5.8 \\ The\text{ radius of the circumscribed circle is 5.8} \end{gathered}`
