Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
The angle in a circle sector is called the "central angle." This angle is formed at the center of the circle and subtends the arc of the sector. It is measured in degrees or radians and determines the size of the sector.
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
area of sector = (angle at centre*area of circle)/360
(pi * radius squared) * ( sector angle / 360 )
There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.
It is found by: (sector area/entire circle area) times 360 in degrees
Area of a sector of a circle.
The area of the circle is(17,640)/(the number of degrees in the central angle of the sector)
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
The area of the sector of the circle formed by the central angle is: 37.7 square units.
