It is: 110/360*pi*12*12 = 44*pi square units
just multiply the two numbers
It is difficult to say since there is no image and it is not clear what part is shaded. But, if there is a circle with a 12 metre diameter which contains two equal circles which are as large as possible, then the shaded area is probably 56.55 square metres.
If I understand you correctly, if 11/12 of the circle is shaded, then 1/12 is not shaded.
A sector is a part of a circle which looks the same shape as a piece of a circular pie. You probably remember that Pi charts look like a circular cake cut into portions. We can calculate the area of the sector of a circle if we know the angle between the two straight sides and the radius of the circle. Now the area of a complete circle is Pi x square of radius, If the radius is 12 cm then the circle's area will be Pi x square of 12 square centimetres. But that is for the full circle. If the sector's angle is 60 degrees, that would mean that the area of the sector would be 60 degrees/360 degrees which equals 1/6; so finally, the area of the sector is (Pi x 12 squared) divided by 6 = 75.398 sq cm )correct to 4 decimal places).

find the area of the shaded sector 12cm and 24°
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 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
Area = pi*122 = 144pi square units Shaded area = (260/360)*144pi = 104pi square units
area of whole circle = pi * radius squared = 3.14159 * 36 = 113.1area of sector = 113.1 * ( 10 / 360 ) = 3.14159 sq units
It is: 110/360*pi*12*12 = 44*pi square units
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.

if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
just multiply the two numbers
The area of a sector of a circle with radius 12 and arc length 10pi is: 188.5 square units.
