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
For the conical portion
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.
