If the area of circle O is 16π, what is the length of an arc on the circle formed by a central angle measuring 30 degrees? Choose the correct choice from the following options:
A) π B) 3π/2 C) 2π/3 D) 5π/2 E) 8π
Area = 16π   Radius = 4   Circumference = 2 x 4 x π = 8π   Angle forming the arc = 30 degrees. 30/360 = 1/12.   Therefore length of arc = 1/12 * 8π = 2π/3 - Answer choice 2π/3.
