A cone has a circular base of radius 24 m and height of 10 m. The canvas used to make the tents costs 70 per sq .m.​

Answer 1

Step-by-step explanation:

Total area of each Tent (Cylinder) =2πrh

=2×

7

22

×2.8×3.5

=61.6 m

2

Area of conical upper part (cone) = πrl

=

7

22

×2.8×

+2.8

=30.8 m

2

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

=61.6+30.8

=92.4 m

2

Cost of making Tent = Rs. 120 per m

2

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)
