Hey buddy,
● Answer -
Cost of cloth = 37125 Rs.
● Explaination-
# Given-
r = 105/2 = 52.5 m
l = 5 m
# Solution-
Curved surface area of cylinder
A1 = 2πrl
A1 = 2 × 22/7 × 52.5 × 5
A1 = 1650 m^2
Curved surface area of cone
A2 = πrl
A2 = 22/7 × 52.5 × 5
A2 = 825 m^2
Total cloth required
Cloth = A1 + A2 = 1650 + 825 = 2475 m^2
Cost of cloth = 2475 × 15
Cost of cloth = 37125 Rs.
Hope this is useful...
