5. a) Determine the total surface area of this tent, including the floor, in order to
estimate the amount of canvas needed
to construct it.
b) What is the volume of the tent?

Step-by-step explanation:

Radius of the conical part = radius of cylindrical part r=

Slant height of the cone l=2.8 m

Height of the cylinder, h=2.1 m

Canvas needed to make the tent = Curved surface area of the conical part + curved surface area of the cylindrical part.

Curved surface area of conical part = πrl=

Total surface area = Curved surface area of conical part + Curved surface area of cylindrical part

canvas = Rs. 500

Cost of 33 m

canvas =33×500=16500

Therefore, it will cost Rs. 16500 for making such a tent.
