The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
It is: 110/360*pi*12*12 = 44*pi square units
An entire circle is 360 degrees. 90 deg is 1/4 of that. Area of a circle is A = pi r^2 area of this sector is (1/4) pi r^2 = (1/4) x 3.14 x 4x4 =12.56
The area of the shaded sector is: 245.7 square units.

The approximate area of the shaded region of 10 cm is 100 square centimeters.
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
We would need to know how big the circle is. And what is the shaded part looks like. That will help us figure out the answer.
area of whole circle = pi * radius squared = 3.14159 * 36 = 113.1area of sector = 113.1 * ( 10 / 360 ) = 3.14159 sq units
0. There is no circle so no shaded area of a circle!
Area of sector = 60/360ths ie 1/6th of the total area; Total area = 12 x 12 x 3.14 = 452.16 cm2 Area of sector = 452.16/6 = 75.36 cm2
