Given
Diameter = 2.8 m
Radius = 1.4 m

Area covered in hundred revolutions
= 100 × Lateral surface area of a cylinder
=100× πrl
= 100×1.4×3.14 ×l
= 43.96 l sq.m

where l = slant height of a cylinder

Diameter = 2.8m
Radius = 1.4m
Slant height. = L

Now area covered in 100 revolutions
= πrL x 100
22/7 x 1.4 x L x 100
440 m^3
