77m² cloth will be required to cover domes.
Step-by-step explanation:
Given: domes of radius 3.5 metres
To find:
How much cloth will be required to cover domes of radius 3.5 metres?
Solution:
The radius of the dome, r = 3.5 meters
Now,
The required area of the cloth to cover the dome is,
= 2x22/7x r x r
substituting r = 3.5 m
= 2x22/7x3.5x3.5
= 2x22/7x12.25
= 77 m²
Thus, 77m² cloth will be required to cover domes.
