\underline{\textbf{Given:}}

\mathsf{Area\;of\;a\;sector\;is\;24\,\pi\;cm^2}

\mathsf{and \;its\;arc\;length\is\;6\,\pi\;cm}

\underline{\textbf{To find:}}

\textsf{Radius of the circle}

\underline{\textbf{Solution:}}

\mathsf{Area\;of\;a\;sector\;=\;24\,\pi\;cm^2}

\implies\mathsf{\dfrac{l\,r}{2}=\;24\,\pi}

\implies\mathsf{\dfrac{(6\,\pi)r}{2}=\;24\,\pi}

\implies\mathsf{(3\,\pi)r=\;24\,\pi}

\implies\mathsf{r=\dfrac{24\,\pi}{3\,\pi}}

\implies\boxed{\mathsf{r=8\;cm}}

\therefore\textsf{Radius of the circle is 8 cm}
