How much 1.25 meter wide cloth will be required to male it?
Answer: (d) 440 m
The radius of a conical tent = 7 meter
The height of a conical tent = 24 meter
Then, the slant height of the cone = sqrt. (7^2 + 24^2)
= sqrt. (49 + 576)
= 25 meter
The surface area of conical tent = pai x r x l
Where, l = slant height, r = radius of the cone & pai = constant.
Then, the surface area of the conical tent = 22 x 7 x 25/7
= 550 m^2
length of the 1.25 meter wide cloth = 550/1.25
= 440 m
Hence, the correct answer is option (d) 440 m.
