Question

a conical tent is made of 4 5 m wide trapalin vertical height of
the conical tent is 4 m and base radius is3 m find the lenght of
the trapalin used ,assuming that 10 % extra material is required
for stiching margins and wastage in cutting (take pie = 3 14)

Let r be the radius, h be the height and l be the slant height of
the given conical tent , then we have:r = 3mh = 4mthen l = h2 + r2
= 42 + 32 = 5mHence, CSA of conical tent = π r l= 3 14 ×
3 × 5 m2= 3 14 × 15 m2= 47 10 m2Area of extra material
required= 10100 × 47 10 m2= 4 71 m2Then total area of
tarpaulin required= 47 10 + 4 71= 51 81 m2Now breadth of tarpaulin
= 4 5 mHence, length of tarpaulin = total area of tarpaulinbreadth
= 51 814 5= 51 8192 = 51 81 × 29 = 103 629 = 11 51mHence,
length of the tarpaulin = 11 51m
