Given:
Radius of the cirle = 11 ft
Angle = 150 degrees
π = 3.14
Let's find the area of the sector of the cicle.
To find the area of the sector, apply the formula:

Where:
π = 3.13
θ = 150 degrees
r = 11
Thus, we have:

Solving further:

Therefore, the sector area of the circle is 158.3 square feet.
ANSWER:
158.3 square feet.
