Question

how many metre of cloth, 2.5m wide, will be required to make a conical tent whose base radius is 7cm and height 24m

Answer 1

Answer:

220 Meters

Step-by-step explanation:

First calculate the length of the tent.

l=√h^2+r^2

on calculation we get :

l = 25 m

Since we require the area of cloth therefore we calculate the curved surface area if the tent.

So, CSA = π×r×l

3.14×7×25=CSA

On calculating we get CSA to be 550 m^2.

Now we need length of the cloth

So area = l×b

550= l×2.5

Therefore l= 220 meter.
