the length l =2.5m, radius r=1.5m
curved surface area=2pi rl=23.5m2
the area of road=16500m2
the revolution taken by the roller=16500/23.5=702
curved surface area=2pi rl=23.5m2
the area of road=16500m2
the revolution taken by the roller=16500/23.5=702

In my answer, I've taken surface area (curved) of roller in decimal. That's, why the answer is coming 700.01.
If you don't take decimal and find the number of Revolutions by dividing 16500 by (165/7), then the answer is perfect.
