What length of tarpaulin 3m wide will be required to make conical tent of height 8m and radius 6m? Assume that the extra length of material that will be required for stitching margins and wastage in cutting is approximately 2.2m (use pie= 3.14) Also find what will be the volume of cylinder if made of same cone’s dimensions?

Answer:
124 m² and 113 m²
Step-by-step explanation:
h = 3 m and r = 6m
l²=r² + h²
l² = 36+9
/² = 45
l =√45 = 6.7m
CSA of cone = πrl
3.14x 6 x 6.7 = 126.2m²
126.2 - 2.2 = 124 m² (Ans.)
Volume of cone = 1/3πr²h
1/3 x 3.14 x6 x 6 x 3 = 113 m² (approx.)
