Answer:
It is given that
Radius of the conical tent = 7m
Height of the conical tent = 24m
We know that
We know that Slant height l =√ (r2 + h2)
We know that Slant height l =√ (r2 + h2) By substituting the values
l = √(72 + 242)
On further calculation
l = √(49 + 576) = √625
So we get
l = 25 m
We know that
We know that Area of the cloth = πrl
By substituting the values
Area of the cloth = (22/7) × 7 × 25
On further calculation
Area of the cloth = 550 m2
We know that
Length of the cloth = area/ width
By substituting the values
Length of the cloth = 550/ 2.5 = 220m
Therefore, 220m of cloth is required to make the conical tent.
