Question

the diameter of a wheel is 1.26 M what the distance covered in 500 revolutions

Answer 1

The distance covered by the wheel in 500 revolutions is 1980.

Step-by-step explanation:

The diameter of a wheel, d = 1.26 m

So, the radius , r = d/2 = 1.26/2 = 0.63 m

We know that the distance covered by the wheel in 1 revolution is equal to the circumference of the wheel, therefore,

The distance covered in 1 revolution is,

= 2πr

= 2 × $\frac{22}{7}$ × 0.63

= 2 × 22 × 0.09

= 3.96 m

                                                       

                                                     

No. of revolutions that the wheel will make is given as 500

Thus,

The distance covered by the wheel in 500 revolutions is ,

= 3.96 × 500

= 1980 m
