**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

Angle of the sector of the Arc (D) =

Angle of the sector of the Arc (D) = (360 * 22)/(2 * (22/7) * 10.5)

Sector angle = 120

The plane figure enclosed by two radii of a circle or ellipse and the arc between them.
