Curved surface area of cylinder =2×22/7×r×h
=2×22/7×42×350
=44×6×350
=92400
Now it takes 500 complete revolutionsto level the road
So the area covered by road =92400×500=46200000cm square
=46200000/100×100
=4620m square
=2×22/7×42×350
=44×6×350
=92400
Now it takes 500 complete revolutionsto level the road
So the area covered by road =92400×500=46200000cm square
=46200000/100×100
=4620m square
