Area of a sector with radius and sector angle - Sector - Mensuration problem solver

Find the area of a sector of radius 3.5 cm whose sector angle is 120 degree.


Radius = 3.5
Sector angle = 120
Area of the Arc = (D/360)*(Pi*r^2) sq.units
Area of the Arc = (120/360) * ((22/7) * 3.5 * 3.5) sq.units
Area = 12.833333333333
Area of the Arc (D/360)*(Pi*r^2) = 12.8333 sq.units
