The area of a sector is the area of the circle multiplied by the fraction of the circle covered by that sector. This is a true statement and correct formula.
That would certainly do it.
Area of a sector of a circle.
The answer depends on what information about the circle is given: area, radius, length and angle of arc, area and angle of sector, etc. In each case, there is a different way to calculate the diameter but, since there is no information on what is known, it is not possible to answer the question.
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).
The area of the sector is: 221.2 cm2
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
The area of a sector is the area of the circle multiplied by the fraction of the circle covered by that sector. This is a true statement and correct formula.
true
Divide the area of the sector by 360 and multiply it to the area. The area of the sector is 5 square inches.
The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
That would certainly do it.
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
