Area of whole circle = pi*r2 = 64*pi Area of Sector = Area of Whole Circle * Angle of Sector/Angle of Whole Circle = Area of Whole Circle * 120/360 = Area of Whole Circle / 3 = 64*pi/3 = 67.0 to the nearest tenth.
No. Assuming the measure of the arc is in some units of length along the curve, you have to divide the result by the circumference of the circle. Basically, you need to multiply the area of the whole circle by the fraction of the whole circle that the sector accounts for.
if given the central angle and the area of the circle, then by proportion: Given angle / sector area = 360 / Entire area, then solve for the sector area
The area of the sector of the circle formed by the central angle is: 37.7 square units.
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.
Divide the area of the sector by 360 and multiply it to the area. The area of the sector is 5 square inches.
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.
Portion of the area of a circle is called a sector.
The area sector of a circle needs pi to work it out.
if a circle has a radius of 12cm and a sector defined by a 120 degree arc what is the area of the sector
49 pi but the circle is 49 and 2
Area of a sector of a circle = (pi) x (radius)2 x (central angle of the sector / 360)
