diameter of Garden roller is 1.4 m and it is 2 m long how much area will it cover in 5 revolution

mysticd Hi ,

Diameter of the roller = d = 1.4 m

Radius ( r ) = d/2 = 1.4/2 = 0.7m

Length of the roller = ( h ) = 2 m

If the roller complete one revolution

Then the area covered = curved surface area of the roller

= 2πrh

Area covered in 5 revolutions

= 5 × 2πrh

= 10 × 22/7 × 0.7 × 2

= 44 square meters

I hope this helps you.

:)
