A chord of a circle of radius \(20 \ cm\) subtends an angle of \(90^\circ\) at the centre. Find the area of the corresponding major segment of the circle. (Use \(pi = 3.14\)).
Solution:
Area of the major sector \(=\) \(cm^2\)
Area of \(\Delta OAB\) \(=\) \(cm^2\)
Area of major segment \(=\) \(cm^2\)
