Q : 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 20 cm (Use ).
Base radius of the conical tent =
Height of the tent =
Curved surface area of a cone =
Area of tarpaulin required = Curved surface area of the tent
Now, let the length of the tarpaulin sheet be
Since is wasted, effective length =
Breadth of tarpaulin =
Therefore, the length of the required tarpaulin sheet will be 63 m.
