SOLUTION
This is a length of arc problem.
The formula for finding the length of an arc is:
[tex]\frac{\theta}{360}\times2\pi r[/tex]r=TR=PT=11ft
[tex]\begin{gathered} \frac{\theta}{360}\times2\pi r \\ r=11ft \\ \theta=164^o \end{gathered}[/tex][tex]\begin{gathered} \frac{164}{360}\times2\pi(11) \\ =\frac{164}{360}\times2\times3.14\times11 \\ =31.4698ft \\ =31.47ft(to\text{ 2 decimal places)} \end{gathered}[/tex]The final answer is 31.47ft.
