12 inches.

Good luck!

Answer:

12 inches

Step-by-step explanation:

2 = arc length

30 degrees = m arc AB

Formula

arc length = m arc AB / 360 degrees (2πr)

Plug in formula

           2 = 30/360 (2πr)

           2 = 60πr/360

  (360)2 = 60πr/360 (360)

       720 = 60πr

720/60π = 60πr/60π

          12 = r
