Question

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

Answer 1

Answer:

h = Height of tent = 8 m

r = Base radius = 6 m

Therefore,

l=

r

2

+h

2

=10 m

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

2

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
