In the picture below, a sector of the circle is shaded yellow.
In the figure below, the length of the angle of a sector in a given circle is 40 degrees and the area of the sector is equal to 20 cm 2. To find the area of a sector, find the area of the whole circle and then multiply by the angle of the sector over 360 degrees. Calculations at an annulus sector (circular ring sector). Is it the arch length or the are of a the perimeter of the sector includes the length of the radius $\times 2$, as well as the arc length.
