Question

a garden roller has a circumference of 3m. how many revolutions does it make in moving a distance of 21 m....?

Answer 1

3m= 1 revolution
so, for 1m= 1/3 revolution
so, 21 m= (1/3)×21 revolution
=7revolution

Answer 2

7 number of revolutions.

Step-by-step explanation:

Given that,

A garden roller has a circumference of 3 m. We need to find the number of revolutions does it make in moving a distance of 21 m.

Since,

1 rotation = 3 m

Using unitary method to find the number of revolutions does it make in moving a distance of 21 m.

x rotation = 21 m

So, there are 7 revolutions it make in moving a distance of 21 m.
