The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.

Because you will be using the number pi to find the area of the circle, some rounding will be required.
If I understand you correctly, if 11/12 of the circle is shaded, then 1/12 is not shaded.

find the area of the shaded sector 12cm and 24°
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
(pi * radius squared) * ( sector angle / 360 )
You find the hundredth place then look at the number behind it. If its greater than 5, round up. If not, round down
area of whole circle = pi * radius squared = 3.14159 * 36 = 113.1area of sector = 113.1 * ( 10 / 360 ) = 3.14159 sq units

The area is r^2*x where r is the radius of the circle and x is the angle measured in radians. If you are still working in degrees then Area = (y/180)*r^2, where the angle is y.
Find the area of the shaded region means find the area of the area that is shaded in or darkened.
It depends on what the shaded and non-shaded parts look like!
