Question

the radius of awheel of a bus is 0.7m.How many rotation wheel complete while travelling a distance of a 22km.

Answer 1

circumference of wheel = $2 \pi r$

Here,

Circumference of wheel = $2$×$\frac{22}{7}$×$0.7$

Circumference of wheel = 2×2.2

Circumference of wheel = 4.4

Now,

it will take ($\frac{22000}{4.4}$) rotations to cover 22 km


it will take 5000 rotations to cover 22 km


 i hope this will help you

Answer 2

Answer:

Wheel would complete 5000 rotation while travelling a distance of a 22 km.

Step-by-step explanation:

The radius of a wheel of a bus = 0.7 m

Circumference of the wheel = 2πr

                                      $=2\times \frac{22}{7} \times 0.7$

                                      = 4.4 meter

1000 meter = 1 km

4.4 meter = $\frac{4.4}{1000}$ = 0.0044 km

Rotation of wheel while travelling a distance of a 22 km = $\frac{22}{0.0044}$

                                                                                              = 5000 rotation

Wheel would complete 5000 rotation while travelling a distance of a 22 km.
