  • Radius (r) = 8m

  • Angle made at centre [tex](\theta)[/tex] = 140°

[tex] \boxed{ \mathrm{length \: \: of \: \: arc = \dfrac{ \theta}{360 \degree} \times 2\pi r}}[/tex]

  • [tex] \dfrac{140}{360} \times 2 \times 3.14 \times 8[/tex]

  • [tex] \dfrac{7}{18} \times 50.24[/tex]

  • [tex] \dfrac{351.64}{18} [/tex]

  • [tex]19.54 \:m[/tex]
