What is the area of the shaded sector

Area of the sector is 558.22ft².

Explanation:

A= N/360(πr²)

where;

N=160°

π=3.14

r=20

A= 160/360(3.14(20)²)

A= 160/360(3.14(400))

A= 160/360(1256)

A=558.22ft.

Recall that area is measured in square units. And the unit of the radius is ft. Therefore our final answer becomes 558.22ft².

Also note that a sector is the part of a circle enclosed by two radii of a circle and their intercepted arc. It iseasily noted to be the pie-shaped part of a circle.
