Answer:

Given : AC = 20 , AB =15 and o is the center of the circle

To find : area of the shaded region

Solution: AC = 20cm

AB = 15cm

BC is Diameter as it passes through O centre of the circle

Hence angle BAC is right angle

=》BC² = AB² + AC² = 20² + 15²

=》BC = 25 cm

Diameter = 25 cm

Radius = 25/2 cm

Area of semicircle = (1/2)22/7 (25/2)²=625 /8 =245.4cm²

Area of right angle = (1/2) * 15 * 20 = 150 cm²

area of the shaded region = 245.4 - 150 = 95.4cm²
