What is the area of the sector that is not shaded?

12
24
120
144

Answer-

The area of the sector not shaded is

Solution-

Here,

The angle of the sector = Θ = 60°

Radius of the circle = 12

Then area of the circle will be,

Putting the values,

We also know that, the area of sector is,

where, angle of the sector is measured in degrees.

Putting the values,

Therefore, the area of the sector not shaded = 144π-24π = 120π
