Question

How many meters of five meters of whole cloth will be required to make conical tent. The r of whose base = 3.5m and h = 12m
please answer as quickly as you can ​

Answer 1

Answer:

thn CSA of conical tent = area of cloth.

hence , 27.5 m cloth is required to make the conical tent.

Explanation:

r = 3.5 m

h = 12 m

slant height l = root of r2 + h2

= root of 3.5 square + 12 square

= 12.5 m

CSA = pi r l

= 22/7 * 3.5* 12.5

= 137.5 m2

let x m of cloth be required to make the tent.

thn CSA of conical tent = area of cloth.

5x = 137.5

therefore , x = 137.5 / 5

= 27.5 m
