Find the area of a sector of a circle with radius 6 cm if angle of the sector is 60°.

Let OACB be a sector of the circle making 60° angle at centre O of the circle



 


Area of sector of angle θ = *πr2


 


Area of sector OACB = * (6)2


 


=


 


= cm2


 


Hence,


 


The area of the sector of the circle making 60° at the centre of the circle is cm2
