Given:
The radius is 18ft.
The angle is
[tex]\frac{\pi}{3}[/tex]
To find:
The length of the arc
Explanation:
The angle in degrees is
[tex]\frac{\pi}{3}\times\frac{180}{\pi}=60^{\circ}[/tex]
Using the formula of the length of the arc is,
[tex]\begin{gathered} s=\frac{\theta}{360}\times2\pi r \\ s=\frac{60}{360}\times2\times\frac{22}{7}\times18 \\ s=18.857 \\ s\approx18.9ft \end{gathered}[/tex]
Final answer:
The length of the arc is 18.9 ft.
