A circus tent is cylindrical upto a height of
3.3 m and conical above it. If the diameter of
the base is 100 m and slant height of the conical
part is 56.4 m, find the total canvas used in

8 per m², find the cost of making the tent.​

Answer 1

csa of cylinder 2pirh

2 ×22/7 ×50×3.3=1037.14

CSA of cone = pi r l

22/7×50×56.4 = 8862.85

total canvas used = 1037.14+8862.85

= 9899.99

cost of canvas =9899.9 × 8= 79199.92
