  • radius=r=7in
  • Angle=135°

We know

  • Length if arc=L


\boxed{\sf L=(\theta)/(360)* 2πr}


\\ \sf\longmapsto L=(135)/(360)*2π(7)


\\ \sf\longmapsto L=(27)/(72)* 14π


\\ \sf\longmapsto L=(27)/(36)* 14π


\\ \sf\longmapsto L=(9)/(12)* 7π


\\ \sf\longmapsto L=(63π)/(12)


\\ \sf\longmapsto L=(21π)/(4)in
