Sector area:

R is the radius of the sector, n is the degree of the arc's central angle, π is the circumference of the circle, and L is the arc length corresponding to the sector. You can also divide the area of ​​the circle where the sector is located by 360 and then multiply it by the angle of the sector's central angle n, as follows: S=nπR2/360.
