What length of tarpaulin 3 m wide will be required to make conical tent of height 8 m
and base radius 6 m? Assume that the extra length of material that will be required for
stitching margins and wastage in cutting is approximately 20 cm (Use pi = 3.14).

Given is a conical tent with :
Height( h ) = 8 meter
Radius ( r ) = 6 meter
Curved surface area of the cone =
= 3.14 x 6m x 10m
The extra length of material that will be required for stiching margins and wastages in cutting is approx 20 cm = 0.2 meter
So, its length = l - 0.2 m
And its width = 3 meter
Area of sheet = CSA of tent
So the area of the tarpaulin = l x b
= l - 0.2m = 62.8m
Therefore, length of the tarpaulin sheet required is 63m.

63 m long trampoline is required.
STEP-BY-STEP EXPLANATION
Height of tent = 8 m
Radius of tent = 6 m
The shape of the tent is conical.
So,
The slant height of the conical tent is equal to :-
Now,
We have
R= 6 m
L= 10 m
And also it is given that value of pie is 3.14
Finding Curved surface area of tent :-
(Area of trampoline required)
So,
The curved surface area of cone is 188.40 m²
Now,
Length of the trampoline = x m
Breadth is given that is 3 m
So,
Area of trampoline = Curved surface area of tent
So,
Now
Extra length required is 20 cm
So,
So,
Actual length of trampoline required is equal to :-
Hence,
Total length of trampoline required is 63 m
