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
