Due to heavy floods in a state, thousands were rendered homeless . 50 schools collectively offered to the state government to provide place and canvas for 1500 tents to be fixed by the government and decided to share the whole expenditure equally. The lower part of each tent is cylindrical of base radius 2.8m and height 3.5m with conical upper part of the same base radius but height 2.1m . If the canvas used to make the tent costs Rs 120 per m² , find the amount shared by each school to set up the tents.

Answer:
Step-by-step explanation:
C.S.A of cylinder =2πrh
=2×22/7×2.8×3.5
=61.6m^2
Slant height of cone = √2.8^2+2.1^2
= 3.5m
C.S.A of cone = πrl
=22/7×2.8×3.5
=30.8m^2
S.A of a tent = 92.4m^2
Cost of one tent = 92.4×120
=11088
Cost of 1500 tents = 1500×11088
= 16632000
Cost shared by each school = 16632000/50
= ₹332640
