What is the area of a shaded circle sector with a radius of 12 and the arc of 110 degrees?
It is: 110/360*pi*12*12 = 44*pi square units
How do you find the area of a shaded area that is 12 in base and 9 inch height?
just multiply the two numbers
The diameter of a larger circle is 12M what is the area of the non shaded part There are tow shaded circles in a bigger one?
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.
How do you find how much of a circle isn't shaded if the part that's not is eleven twelfths?
If I understand you correctly, if 11/12 of the circle is shaded, then 1/12 is not shaded.
What is the formula to calculate sector?
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).
