Diameter of the roller = 1.4m
Radius if the roller = 1.4/2= 0.7m
Length of roller=2m
Area covered in one revolution = CSA of roller = 2 pi r h
= 2x22/7x0.7x2
=8.8m2
Therefore area covered = CSA x no. Of revolutions
=8.8x15
=132m2

diameter=1.4m
so,radius,r=0.7m
h=2m
area covered in one revolution=c.s.a of roller
=2×pi×r×h
=2×22/7×0.7×2
=44/7×1.4
=8.8m^2
so, area covered in 15 revolution=(8.8×15)m^2
=132m^2
so,radius,r=0.7m
h=2m
area covered in one revolution=c.s.a of roller
=2×pi×r×h
