Step-by-step explanation:
radius of big circle = 21m
radius of semicircles =10.5m
area of big circle = 2πr²
= 2×3.14×21×21
=2769.48m²
area of two semicircles = 2(area of one semicircle)
=2×(πr²)
=2×3.14×10.5×10.5
=692.37m²
area of shaded region = area of big circle- areaof two semicircles
=2769.48-692.37
= 2077.11m²
