Angle of sector of an arc with radius - Sector - Mensuration problem solver

length of the arc of a sector is 22 cm and its radius is 10.5 cm. Find its sector angle.


Length of the arc = 22
Radius = 10.5
Length of the arc of sector (D/360) * 2 * Pi * r = 22 units
Angle of the sector of the Arc (D) = (360 * l)/(2 * Pi * r)
Angle of the sector of the Arc (D) = (360 * 22)/(2 * (22/7) * 10.5)
Sector angle = 120
Sector Angle of Length of the Arc (r) = 120 degree
