length of arc PQ = 3.14 meters (option B)

Step-by-step explanation:
\begin{gathered} \text{Length of an arc in radians = r}\theta \\ \end{gathered}

The angle given is in degrees:


\text{length of an arc using angle in degr}ees\text{ = }\theta/360*2\pi r
\begin{gathered} \theta\text{ = 60}\degree \\ PR\text{ = radius =3m } \\ \text{let }\pi\text{ = 3.14} \\ \text{length of arc PQ = }(60)/(360)*2*3.14*3 \end{gathered}
\begin{gathered} \text{length of arc PQ = }(1)/(6)*3.14*6\text{ = 3.14} \\ \text{length of arc PQ = 3.14 meters ( option B)} \end{gathered}
