    Hi boomgoesthegmat,

    This question can be solved by TESTing VALUES.

    We're told that the area of the shaded region is 3 TIMES the area of the central circle...

    Area of center = 1
    Area of shaded region = 3(1) = 3
    Area of FULL CIRCLE = 1+3 = 4

    With those values....
    Radius of center = 1
    Radius of FULL CIRCLE = 2

    The question asks how many times the circumference of the full circle is to the smaller circle...

    Circumference of small circle = 2pi
    Circumference of full circle = 4pi

    Final Answer: C

    GMAT assassins aren't born, they're made,
    Rich
