Question

he radius of a ci The diameter of a wheel is 28 cm. How many revolutions will it make to travel 352m?​

Answer 1

Answer:

Also, the total distance is 352m so, we will convert it in cm by multiplying the value with 100. Hence, the number of revolutions taken to cover the given distance is 400.

Step-by-step explanation:

Answer 2

Answer:

The wheel will make 400 revolution to cover 352m distance .

Step-by-step Explanations :

Given: Diameter of wheel = 28cm

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

Diameter of wheel (D) = 28cm -------- ( given )

We know that,

Radius of wheel (R) = D/2 = 28/2 = 14cm

Also,

Circumference of wheel = 2πR

Substituting the given value in above formula we get,

Circumference of wheel = 2 × 22/7 × 14

= 88cm

= 0.88m ------------( since 1m = 100cm )

So 0.88m 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 = 352/0.88

= 400

Hence the wheel will make 400 revolution to cover 352m distance .
