Answer:

2nd option

Step-by-step explanation:

the length of the arc is calculated as

arc = circumference × fraction of circle

     = 2πr × [tex]\frac{120}{360}[/tex] ( r is the radius )

    = 2π × 10 × [tex]\frac{1}{3}[/tex]

    = 20π × [tex]\frac{1}{3}[/tex]

   = [tex]\frac{20\pi }{3}[/tex] in
