$Arc \: length = 2 π r × \frac{θ}{360°} \\ Arc \: length = 2π \times 8 \times \frac{40}{360} \\ s = 2 \times \frac{22}{7} \times 8 \times \frac{40}{360} \\s = \frac{14080}{2520 } \\ s = 5.587 \: approx$

solution

\begin{gathered}Arc \: length = 2 π r × \frac{θ}{360°} \\ Arc \: length = 2π \times 8 \times \frac{40}{360} \\ s = 2 \times \frac{22}{7} \times 8 \times \frac{40}{360} \\s = \frac{14080}{2520 } \\ s = 5.587 \: approx\end{gathered}
