given,
length of roller (L) = 2 m
radius of roller(r) = 168/2 = 84cm =0.84 m
then,
area of road that is covered by road roller in one complete revolution
= curved area of roller
= 2πr × L
= 2×3.14 × 0.84 ×2
= 10.55 m^2
hence total area covered in 959 complete revolution = 10.55×950 =10022 m^2
I hope this will help you....
