A road roller is used to press a ground of area 2200 sq. meter. How many rotations does it make?
(1) The diameter of the road roller is 1.75 m.
(2) The breadth of the road roller is 2 m.
In order to find out the number of rotations we need the area of the cylinder. So, we need both the height and the diameter of the cylinder(roller)
Hence answer is C
and calucaltion for the same is
Number of rotations = 2200/(2pie *r * h)
where r = 1.75/2 m and h = 2m
So, number of rotations will be 100
Hope it helps!
