The area of a sector is 0.5*r^2*theta square units where r is the radius measured in linear units and theta is the angle (measured in radians).
Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
area of sector = (angle at centre*area of circle)/360
It depends on what information you have: the radius and the area of the sector or the length of the arc.
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/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o
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 sector = (angle at centre*area of circle)/360
To find the area of the shaded sector, first determine the area of the entire circle using the formula (A = \pi r^2), where (r) is the radius of the circle. Next, find the fraction of the circle represented by the sector by dividing the central angle of the sector (in degrees) by 360 degrees or using the angle in radians divided by (2\pi). Multiply the area of the circle by this fraction to get the area of the shaded sector.
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.

If you have the arc length:where:L is the arc length.R is the radius of the circle of which the sector is part.
Multiply ( pi R2 ) by [ (angle included in the sector) / 360 ].
It depends on what information you have: the radius and the area of the sector or the length of the arc.
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
It is found by: (sector area/entire circle area) times 360 in degrees
