If the area of circle O is 16π, what is the length of an arc on the circle formed by a central angle measuring 35 degrees?	Answers:
A) π
B) 3π/2
C) 2π
D) 5π/2
E) 7π/9
Area = 16π   Radius = 4   Circumference = 2 x 4 x π = 8π   Angle forming the arc = 35 degrees. 35/360 = 7/72.   Therefore length of arc = 7/72 * 8π = 7π/9 - Answer choice 7π/9.
