Given that,

Height (h) of the cylindrical part = 2.1 m

Diameter of the cylindrical part = 4 m

Radius of the cylindrical part = 2 m

Slant height (l) of conical part = 2.8 m

Area of canvas used = CSA of conical part + CSA of cylindrical part

Cost of 1 m^{2} canvas = Rs 500

Cost of 44 m^{2} canvas = 44 × 500 = 22000

Therefore, it will cost Rs 22000 for making such a tent.
