surface area of roller =2pi.r.h
=22/7 x 1.4 x 2 =8.8 m^2
now ,
area covered by roller in one revolution =surface area of roller
hence ,
area covered by roller in 50 revolution =50 x surface area of roller
=50 x 8.8 = 440 m^2
=22/7 x 1.4 x 2 =8.8 m^2
now ,
area covered by roller in one revolution =surface area of roller
hence ,
area covered by roller in 50 revolution =50 x surface area of roller
=50 x 8.8 = 440 m^2
