Question

Find what length of canvas 2 m in width is required to make a conical tent 20 m in diameter and 42 m in slant hight

Answer 1

Solution

Area of cone= pi r l

= 22/7* 10* 42

= 220*6

= 1320 m^2

Now, area of tent= area of canvas

=> 1320= 2* Length

=> Length= 660m

so, length of canvas required= 660m
