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.

The area sector of a circle needs pi to work it out.

That would certainly do it.

Area of sector/Area of circle = Angle of sector/360o Area of sector = (Area of circle*Angle of sector)/360o

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 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 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

area of sector = (angle at centre*area of circle)/360
