Due to heavy floods in a state, thousands were rendered
homeless. 50 schools collectively offered to the state government
to provide place and the canvas for 1500 tents to be fixed by the
governments and decided to share the whole expenditure
equally. The lower part of each tent is cylindrical of base radius
2.8 cm and height 3.5 m, with conical upper part of same base
radius but of height 2.1 m. If the canvas used to make the tents
costs Rs. 120 per sq. m, find the amount shared by each school to
set up the tents. What value is generated by the above problem?

Answer:
Total area of each Tent (Cylinder) =2πrh
=2×

×2.8×3.5
=61.6 m

Area of conical upper part (cone) = πrl
=

=30.8 m

Area of 1500 tents = Area of cylinder + Area of cone
=61.6+30.8
=92.4 m

Cost of making Tent = Rs. 120 per m

Total money cost for canvas =120×90.4
= Rs. 11088
Amount shared by each school =
Number of school
Total amount
=
50
11088
= Rs. 221.76
Therefore, the amount shared by each school to set up the tents = Rs. 221.76=Rs.222 (approx)
