Given :
Cylinder , h= 5m
Cone , d= 105m , r = 105/2 , l = 50m
r of cone = r of cylinder
To find :- CSA of the tent + cost
CSAof tent= CSA of cylinder + CSA of cone
Proof : CSA of cylinder =
2πrh
2×22/7×105/2×5
22×15×5
22×75
1650m sq
CSA of cone =
π×r×l
22/7×105/2×50
11×15×50
550×15
8250m sq
CSA = 1650+ 8250 =9900m sq
cost = 15 × 9900 = 1,48,500rupees
