If the area of circle O is 16π, what is the length of an arc on the circle formed by a central angle measuring 10 degrees?	Choose the correct choice from the following answers.
A) π
B) 2π/9
C) 2π
D) 5π/2
E) 8π
Area = 16π   Radius = 4   Circumference = 2 x 4 x π = 8π   Angle forming the arc = 10 degrees. 10/360 = 1/36.   Therefore length of arc = 1/36 * 8π = 2π/9 - Answer choice 2π/9.
