Area of a sector of a circle = (pi) x (radius)2 x (central angle of the sector / 360)
Divide the angle sector by 360 and multiply it by 24 square meters. The area is equal to 3 square meters.
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.
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
The area enclosed by a chord is equal to the area enclosed by a segment minus the area enclosed by the triangle with the same corners as the segment. To visualise it, draw a circle and put a chord on it. Label the chord AB and the centre of the circle C. The area of sector AB equal to the area of sector ABC minus the area of triangle ABC.
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.
Area of a sector of a circle.
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
Portion of the area of a circle is called a sector.
The area sector of a circle needs pi to work it out.
Area of a sector of a circle = (pi) x (radius)2 x (central angle of the sector / 360)
