$\bf \textit{arc's length}\\\\
s=r\theta \quad 
\begin{cases}
r=radius\\

------\\
r=27\frac{2}{5}\\
\theta =\frac{7\pi }{4}
\end{cases}\implies s=27\frac{2}{5}\cdot \cfrac{7\pi }{4}\implies s=\cfrac{27\cdot 5+2}{5}\cdot \cfrac{7\pi }{4}

s=\cfrac{137}{5}\cdot \cfrac{7\pi }{4}\implies s=\cfrac{959\pi }{20}$
