Given
Find
Length of arc
Explanation
Length of arc is given by
[tex]\frac{\theta}{360}\times2\pi r[/tex]
so ,
[tex]\begin{gathered} \frac{120}{360}\times2\pi(10) \\ \\ \frac{1}{3}\times20\pi \\ \\ \frac{20\pi}{3} \end{gathered}[/tex]
Final Answer
Hence , the length of arc is
[tex]\frac{20\pi}{3}[/tex]
