Question

cylinder shape road roller is 3.5 metres long and has a radius of fun metre find the area levelled by the road roller when it makes 200 revolutions​

Answer 1

Step-by-step explanation:

Radius of road roller=5m

Height of road roller=3.5m

Curved surface area of road roller

$2\pi \: rh$

=2×22÷7×5×3.5

$110m^{2}$

Area levelled =No. of revolutions × C.s.a

=110×200

$22000m ^{2}$
