Answer:

we know,

area of circle = πr²

area of semicircle of circle having diameter of 16.

according to formula = πr²

radius = 16/2 = 8 cm

22/7 × (8)² → 22/7 × 64 → 1408/7 = 201.14/2 = 100.57 cm (approx.)

area of semicircle of circle having diameter of 20 cm.

22/7 × 20² = 22/7 × 400 = 8800/7 = 1257.14/2 = 628.57

to get the area of shaded part 628.57 - 100.57 = 528 cm² (approx.)

hope this helps you!
