Answer 1

Answer:

See whether it is correct . I have tried my best to write a correct answer

Step-by-step explanation:

Area of road =100× area covered in 1 revoluation

=100× lateral surface area of road

=100×2 Area of road =100× area covered in 1 revoluation

=100× lateral surface area of road

=100×2πrh

Given,  d=140cm⇒L=2 m→  100

h=1m

=750×2×

140  ×  100

2m ~ 1

=  100

1500×132

=1980m
