Answer: 9pi (choice B)

====================================================

Work Shown:

C = 2*pi*r .... circumference equation

6pi = 2pi*r .... replace C with the given circle perimeter

6 = 2r .... divide both sides by pi, they cancel

6/2 = r

3 = r

r = 3 ... is the radius

------------

A = pi*r^2 .... area of circle equation

A = pi*3^2

A = pi*9

A = 9pi .... which points to choice B as the final answer
