lateral surface area of cylinder which is also equal to the lateral surface area of road roller=πr²h=22/7×0.35×0.35×1.5m=0.5775m²
area of the field will be 50 ×33=1650
now now divide the area of filled by the lateral surface area of of cylinder I.e. road roller to get the number of rounds...
=1650/0.5775=2858 rounds aprrox...
