Answer: Your answer should be 8.5 π

The formula to find the length of an arc is:

m ∘ 360 ∘ 2 π r  

120 /360  2 π ( 12.6 )

120 /360  25.2 π

Simplify  120 /360  to  1 /3  and finish the other simplifying:

1 /3  25.2 π

25.2 /3 π

Since they want the answer expressed by  π ,  8.5π  is the answer.
