Okay so the area of the ENTIRE circle is PI*r^2
= 3.14159 * 6 * 6
=113.097
Area of shaded portion is 120 degrees which is one third of a whole circle (360 degrees)
Area of shaded portion = 113.097 / 3 =
37.699 or 
37.7 rounded
and that's 37.7 square feet

I guess you need the length of the arc too

circumference of entire circle:
circumference = PI * diam = PI * 2 * radius
circumference = PI * 2 * radius
circumference = 37.699
arc = cirumference / 3 =
12.566 feet
