Given , diameter =1.4m
Therefore , radius =0.7m
and length=2m
Now,
Area covered in one revolution=2pierh
=2×22/7×7/10×2
88/10=8.8m^2
Thus area covered in 50 revolution=8.8×50m^2=440m^2
Hope u find it helpful .

Here is your answer
Given,
diameter of the garden roller = 1.4m
So radius of the garden roller = 0.7m{r}
length = 2m = height {h}
Now, remember
Curved surface area of cylinder= 2πrh
Now, According to the question=>
Maximum area covered by garden roller in 50 revolutions---
50×(2πrh)
=>100π(0.7×2)
=>440 m^2
So,the maximum area covered in 50 revolutions is 440 m^2.
thanks
