Step-by-step explanation:
To Cover Dome we need to cover Curved surface area only with cloth
as base is on ground
CSA of Hemisphere = 2 πr²
r = 2.5 m
CSA of one Dome = 2 π(2.5)²
CSA of two Domes = 2 x 2 π(2.5)²
= 25π m²
π = 22/7
= 25 x 22/7
= 78.57 m²
78.57 m² cloth material will be required to cover 2 big domes each of radius 2.5metres
