The area of the shaded sector is: 245.7 square units.
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
Assuming the shaded sector has the angle of 100o (without seeing the diagram, it could be the other sector, ie the one with an angle of 260o): The sector is 1000 ÷ 360o = 5/18 of the circle. Thus its area is 5/18 that of the circle: area = 5/18 x π x 82 ~= 55.9 units2
Area of the circle = pi*82 = 201.0619298 square units Area of the sector = 290/360 of 201.0619298 = 161.9665546 or about 162 square units
The area of the whole circle is pi*r2 = 25*pi To go any further, you need to assume that the central angle is given in degrees. If the sector is 18.0 degrees out of a circle of 360 degrees so the sector represents 18/360 = 1/20 of the whole circle. The area of the sector, therefore, is 1/20 of the area of the whole circle = 25*pi/20 = 5*pi/4 or 1.25*pi = 12.566 sq inches.

0. There is no circle so no shaded area of a circle!
find the area of the shaded sector 12cm and 24°

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.
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
It is: 110/360*pi*12*12 = 44*pi square units
(pi * radius squared) * ( sector angle / 360 )
That will depend on the length or angle of the arc which has not been given
