A chord of a circle of radius 14 cm makes a right angle at the center. Find the areas of the minor and major segments of the circle.

Open in App
Solution


Radius of the circle =14 cm

Central angle for minor sector =90

Area of the minor sector =θ360×πr2

=90360×227×142

=22×7=154 cm2

So, area of minor segment = Area of sector - Area of triangle AOB

=15412×14×14=15498=56 cm2

Area of the major sector= Area of circle - Area of minor segennt

=π×14256

=227×14×1456

=61656=560 cm2
