Question

How many meters of clothes, 5m wide, will be required to make a conical tent, the radius of whose base is 7m and hight, H =24m.

content quality required

Answer 1

Hay!!

We know that Radius of Tent, R=7m
And it's height, H=24m

Then first we found l =>
$\sqrt{ {r}^{2} + {h}^{2} }$
=>
$\sqrt{( {7})^{2} + ( {24})^{2} m} \\ \sqrt{625m} = 25m$
Area of the curved surfaces =
$\pi \: rl$
(22/7×7×25)m²=>550m²

Thus, the area of clothes =550m²

Length of clothes required =(area/width)

=> 550/5=110m.

Hence, Length of cloth require is 110m.

I hope it's help you

Answer 2

Answer:

110 m.

Step-by-step explanation:

Given, r = 7 m

h = 24 m

∴ slant height l = √(r2 + h2) = √(49 + 576) = √625 = 25 m

CSA of the cone = πrll = 22/7 x 7 x 25 = 550 m2

Area of the cloth used = 550 m2

Given, width of the cloth = 5 m

Length of the cloth used = Area/Width = 550 / 5 = 110 m.
