Due to heavy floods in a state , thousands were rendered homeless, 100 schools of a state collectively offered to the state government to provide place and the canvas for 100 tents to be fixed by the government and decided to share their whole expenditure equally. The lower part of each tent is cylindrical of base radius 2 m and height 2.1 m , with conical upper part of same base radius with a slant height 2.8 m. If the canvas used to make the tent cost Rs 500 per m^2 then find the amount shared by each school to set up the tents. What value is generated by the above problem ?

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 government and decided to share the whole expenditure equally. The lower part of each tent is cylindrical of base radius 2.8 m 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 ? (Use pi = (22)/(7) )
