Question

5.
Due to heavy floods in state, thousands were rendered homeless. 50 schools collectively offered
to the state government the place and the canvas for 1500 tents that to be fixed by the
government and decided to share the whole expenditure equally. The lower part of each tent is
cylindrical of base 2.8 m and height 3.5 m and upper part is conical of same base radius but of
height 2.1 m. if the canvas used to make the tents costs 120 per sq. m, then find the amount
shared by each school to set up the tents.​

Answer 1

$\huge{\mathcal{\purple{A}\green{N}\pink{S}\blue{W}\purple{E}\green{R}\pink{!}}}!$

total area of each Tent (Cylinder) =2πrh

=2×722×2.8×3.5

=61.6 m2

Area of conical upper part (cone) = πrl

=722×2.8×2.12+2.82

=30.8 m2

Area of 1500 tents = Area of cylinder + Area of cone

=61.6+30.8

=92.4 m2

Cost of making Tent = Rs. 120 per m2

Total money cost for canvas =120×90.4

= Rs. 11088

Amount shared by each school =Number of schoolTotal amount

=5011088

= Rs. 221.76

Therefore, the amount shared by each school to set up the tents = Rs. 221.76=Rs.222 (approx)

Answer 2

Answer:

Due to heavy flood in a state thousands were rendered ... the canvas for 1500 tents to be fixed . the lower part of each tent is ... Number of School to share the cost = 50
