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

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

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.
