Find the area of the sector of a circle of radius r and central angle θ.
The area of the sector is the total area subtended by an arc at the center.
θ/ 360) π r 2 is the area of the sector of a circle of radius r and central angle θ.
The area of a sector can be determined by the area of a sector formula which is given by:
θ = an angle subtends by the arc.
Let's take an example:
The area under an arc that subtends an angle of 90º at the center of a circle with a radius of 7 units can be determined by the formula given above.
