You are given with the Area of Larger Circle, from that you can find Radius...

$Area = 36 \pi \quad inch^2 \\ \pi R^2 = 36 \pi \quad inch^2 \\ R = 6 \quad inch$

so its b?

Thnx

If I let radius of smaller circle is r, then R = 2r = D = Diameter of smaller circle: $Circumference = \pi \times Diameter = \pi \times D = \pi \times (2r) = \pi \times R = 6 \pi \quad inches$
