Question

Find the distance covered by a wheel of radius 1.4 m, if it makes 250 revolutions. show working too

Answer 1

`\text{Radius} = 1.4 m`

`\text{Distance covered in One revolution} = 2\pi r`

`2\pi r =`

`2*22=(1.4)/(7)`

`= 8.8 \ \text{m}`

`\text{Distance covered in 250 revolutions}`

`= 8.8 \ \text{m}* 250`

`\bold{= 2200 \ m}`

Answer 2

The distance covered by a wheel is given by the formula:

distance = circumference of the wheel x number of revolutions

The circumference of the wheel can be found using the formula:

circumference = 2πr

where r is the radius of the wheel.

Substituting the given values, we get:

circumference = 2π(1.4) = 2π(1.4) = 2(22/7)(1.4) = 8.8 meters

Therefore, the distance covered by the wheel in 250 revolutions is:

distance = 8.8 x 250 = 2200 meters

So, the wheel covers a distance of 2200 meters if it makes 250 revolutions.
