**The radius of a sector is 2.8 cm. its sector angle is 60 degree. Find the length of the arc.**

Radius = 2.8

Sector angle = 60

Length of the arc formula = units

Length of the arc = (60/360) * 2 * (22/7) * 2.8 units

Length of the arc = 2.9333

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