Answer:

The wheel will make 200 revolution to cover 352m distance .

Step-by-step Explanations :

Given: Radius of wheel (R) = 28cm

To find : How many Revolution will the wheel make to travel 352m = ?

Radius of wheel (R) = 28cm -------- ( given )

We know that,

Circumference of wheel = 2πR

Substituting the given value in above formula we get,

Circumference of wheel = 2 × 22/7 × 28

= 176cm

= 1.76m ------------( since 1m = 100cm )

So, 1.76m is the Distance covered by wheel in 1 revolution.

Therefore the total number of revolution it takes to cover 352m is ,

No of revolution = total distance / distance covered in 1 revolution

Substituting the values in above formula we get,

No of Revolution = 352/1.76

= 200

Hence the wheel will make 200 revolution to cover 352m distance .
