The area of the shaded sector of a circle is 64 pie cm^2
Here we are given that there is a circle: whose radius is cm and the angle formed by two radius that is angle of the sector is
.
The area of the sector of circle is basically the area of the arc of a circle.
The two combination of two radii forms the sector of a circle while the arc is in between these two radii.
Area of sector is given by:
.л
Substituting the given value in the formula of area of sector:
Area of sector is=
We get after solving,
Area of sector= pie cm^2
So from the given options, option 4 is correct.
Hence the area of the sector is 64 pie cm^2
