19. TBQ - Area of major and minor sector

A chord of a circle of radius \(3 \ cm\) subtends \(60^{\circ}\) at the centre. Find the area of the corresponding: (i) minor sector (that subtends \(60^{\circ}\) at the centre), and (ii) major sector (that subtends \(300^{\circ}\) at the centre). (Use \(\pi \approx 3.14\))

 

 

Area of minor sector \(=\) 4.71-0.2914.71 \(cm^2\)

 

Area of major sector \(=\) 23.5513.5543.55 \(cm^2\)
