**Disclaimer** Hi there! I am not fully sure what [ T ] represents. From the answer that I got [ 38π / 3 ], it does not match any one of them, so I choose none of the above. If there's a specific meaning of [ T ] and I am incorrect, please let me know and I will modify my answer.

Answer: None of above

Explanation:

Given formula

S = r θ

  • S = arc length
  • r = radius
  • θ = angle in radians

Given information

radius = 19 ft

Angle = 2π / 3

Substitute values into the formula

S = r θ

S = (19) (2π / 3)

Simplify by multiplication


\Large\boxed{S=(38\pi)/(3) }

Hope this helps!! :)

Please let me know if you have any questions
