Solution

Dear student
r=Radius of circumcircle=3cmWe know that in a right angled triangle, the circumcentre is the mid-point of the hypotenuse.So, Hypotenuse=2r=2×3=6cmNow, Altitude drawn to hypotenuse=2cmThen,area of triangle=12×6×2=6cm2Area of circle=3.14×3×3=28.26cm2Sum of area of disjoint segments=Area of circle-Area of triangle=28.26-6=22.26cm2
