Answer:
2165.34 square yards
Step-by-step explanation:
It is as simple as finding the area of a circle. The given figure is a small sector of a circle with given angle '∅' and radius 'r'.
A circle completes
° to complete its whole area.
So, we can find area of a sector of a circle by the formula =(∅/
°)
²
To find area of semicircle we take as
area of semicircle=
² or (
°/
°)
² : as semicircle forms ∠180°

Similarly, for above figure given values are ∅
° and
yards
So, the area of the given sector is = (
°/
°)
= 
Area of the sector = 2165.34 square yards
