Open in App
Solution


Given radius(r)=14cm

Area of sector OABO=θ360oπr2

Area of sector OABO=90o360o×227×(14)2=154cm2

Area of right angled OAB=12×14×14=98cm2

Area of the minor segment of the circle = Area of sector OABO - Area of righta angled ABO

Area of the minor segment of the circle =(15498)cm2=56cm2

Area of circle =πr2=227×14×14=616cm2

Area of the major segment of the circle = Area of circle - Area of minor segment.

Area of the major segment of the circle =(61656)cm2=560cm2
