Answer 1

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
CSA of tent = CSA of cylinfer + CSA of cone

Proof :
curved surface area of cone = 22/7 x 52.5 x 50 = 8250 
curved surface area of cylinder = circumference of base x height 
circumference of base = 22/7 x 105 = 330 
curved surface area of cylinder = 330x5=1650 
total surface area is 1650 + 8250 = 9900 
cost =9900
