5. 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 20cm (Use Tt= 3.14).

1. Hight of conical tent,h=8 m

Radius of base of tent,r=6 m

Stant height of tent, __________________________      __________________________ CSA of conical tent,   __________________________

Let the length of tarpaulin sheet required be L

As, 20 cm will be wasted,therefore,

Effective length will be (L – 0.2 m)

Effective length will be (L – 0.2 m)Breadth of tarpaulin = 3 m (given)

_________________________      Therefore, the length of the tarpaulin required is 63 m.

h = Height of tent = 8 m

r = Base radius = 6 m

Therefore,

l=

r

+h

=10 m

Curved surface area of the cone = πrl=3.14×6×10 m

Therefore, length of 3 m wide tarpaulin required =

3

3.14×6×10

=62.8 m

Extra length required = 0.2 m

Therefore, total length required = 63 m
