Answer 1

I hope this helps you

Answer 2

Answer:

Rs 6468

Step-by-step explanation:

we have to find the inside distance and outside distance.

for inside distance , radius = 140/2 =70 m

length of circumference =2π×radius

                                      =2×(22/7)×70

                                      =440 m

now, outside distance 

radius = 70 +7 = 77 m

length of circumference = 2π× radius

                                      = 2×(22/7)×77

                                      = 484 m

total length = 440 +484 =924 m

cost = Rs 7× 924 = Rs 6468
