Answer :

Diameter =0.9 m ∴r=0.45 m

Height =1.8 m

Number of rotations = 500

Area of the ground pressed by the roller in one rotation = curved surface area of the roller.

= 2

=

=5.0868 m^{2}

∴ Area of the ground pressed by the roller in 500 rotations.

= ^{2}

= 2543.4 m^{2}

∴ Area of the ground pressed by the roller is 2543.4 m^{2}
