Q13 of 37 Page 13

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


Given: Radius of circle = 14cm


and ∠AOB = 90°





=154cm2


and Area of major sector = Area of circle - Area of minor sector


= πr2 - 154



= 22 × 2 ×14 – 154


= 462cm2
