Answer:
For conical tent.....given..height= 8m, radius=6m....therefore length = root of r square + h square = root of 6 square + 8 square= root of 36+64= root of 100= 10m...width of the tarpaulin = 3m....therfore length of the tarpaulin = 188.4÷3= 62.8m...extra length of material required= 20cm = 0.2m(convertng cm to m)....Actual length of tarpaulin required= 62.8m + 0.2m = 63m..........
