Given : d = 75 cm , width = 105 cm
Circumference of the roller = πd = 3.14×75
= 235.5 cm
= length of path traced in one complete revolution by the roller
Area covered in one revolution
= circumference × width
= 235.5 × 105 cm^2
= 24727.5 cm^2
So, area covered in 14 revolution
= 14 × 24727.5 cm^2
= 346185 cm^2
So, garden roller will cover 346185 cm^2
in 14 revolutions.
