Answer
Given:
Diameter of the roller = 1.4 m
Length of the roller = 2 m
Number of Revolutions = 50
Radius of the roller = = 0.7 m
As we know, the curved surface area of cylinder = 2πrh
The curved surface area of cylinder is 8.8 m2.
Maximum area covered by the roller = Curved surface area x Number of revolutions
= 8.8 x 50
= 440 m2
Hence, the maximum area covered by the garden roller in 50 revolutions is 440 m2.
