Hey mate,
◆ Answer- 46200 Rs
◆ Explanation-
# Given-
Inner radius r = 3 cm
Outer radius R = 3 + 1 = 4 cm
Length l = 1 m = 100 cm
Volume of inner side
V1 = πr^2l
V1 = 3.14 × 3^2 × 100
V1 = 2826 cm^2
Volume of outer side
V2 = πR^2l
V2 = 3.14 × 4^2 × 100
V2 = 5024 cm^2
Volume of rigid pipe
V = V2 - V1
V = 5024 - 2826
V = 2198 = 2200 cm^2
Total cost = 2200 × 21
Total cost = 46200 Rs.
Total cost of forming the pipe will be 46200 Rs.
Hope that is helpful...
