Question

what length of 5 m wide cloth will be required to make a conical tent the radius of whose base is 7m and height is 24m

Answer 1

Answer :

Length of cloth required 110 metre.

Step-by-step explanation :

Given,

Radius of the tent, r = $7$ metre

Height of the tent, h = $24$ metre

Width of the cloth = $5$ metre

In order to find the length of the cloth required, we first need to find the curved surface area and then divide it by width of the cloth. To find the curved surface area of the cloth, we need slant height. So,

Slant height -

$\implies l^{2}=\sqrt{r^{2}+h^{2}}$

$\implies l^{2}=\sqrt{7^{2}+24^{2}}$

$\implies l^{2}=\sqrt{625}$

$\implies l=25$ metre

Now, curved surface area -

$\implies\pi rl$

$\implies\frac{22}{7}\times 7\times 25$

$\implies 550\:m^{2}$

Length of cloth required -

$\implies\frac{Area}{Width}$

$\implies\frac{550}{5}$

$\implies 110$ metre
