Answer:
Answer:
Given :-
The diameter of the wheel of a vehicle is 1.4 m.
To Find :-
How many rotations will the wheel complete in traveling a distance of 2.2 km.
Formula Used :-
where,
r = Radius
Solution :-
First, we have to find the radius,
As, we know that,

Hence, the circumference of a circle is 4.4 m.
Now, we have to find how many rotations will the wheel complete in traveling a distance of 2.2 m,
As we know that,
✧ 1 kilometres = 1000 m ✧
Then, 2.2 km = 2.2 × 1000
2200 m
Hence, number of rotation will be,
