Question

the diameter of a garden roller is 1.4m and it is 2m long how ​

Answer 1

Step-by-step explanation:

Area covered = Curved surface × Number of revolutions

r=

2

1.4

=0.7 m

h=2 m

Curved surface = 2πrh=2×

7

22

×0.7×2=8.8 m

Hence,

Area covered = 8.8×5=44 m

Answer 2

Answer:

Area covered = 8.8×5=44m²

Step-by-step explanation:

Area covered = Curved surface × Number of revolutions

r=  1.4 /2

=0.7 m

Curved surface = 2πrh=2× 22/7×0.7×2=8.8 m²

Hence,  Area covered = 8.8×5=44 m ²
