Expert Answer:

the cost of canvas will depend on the surface area of the tent=CSA.of the cylindrical portion+ Csurface area of the conical portion. For the cylin radius =15 m height=5.5 So CSA=2*(22/7)*15*(5.5) For the conical portion r=radius=15 m straight height =8.25-5.5=2.75 So, l=slant height of the cone= then the CSA of cone= Add the two values of CSA ( cylin and cone) multiply the total by 45( as the rate for 1 sq m is Rs. 45) and you will have the answer.
