We have to calculate the area of the sector. From the picture we can see
that the radius of the circle is: r = 10 ft. The area of the circle is:
A = r^ 2 Pi = 10^2 * 3.14 = 100 * 3.14 = 314 ft^2. We have to find
which part of the circle is the sector. 360 deg : 40 deg = 9. Then we
will divide the area by 9. 314 : 9 = 34.89 ft^2. Answer: C ) 34.89 ft^2
