Question

the radius of a wheel of a bus is 0.70 m. How many revolutions will it make in covering 22 km





PLEASE ANSWER ​

Answer 1

Answer:

hii mate hope my answer finds you in the pink of your health----

Step-by-step explanation:

given, the radius of a wheel=0.70m.

1 revolution by the wheel of the bus

=C.S.A of the wheel

= 2×PIE×R(R=0.70m)

=2×22/7×0.70

=44×0.10

=4.4m

therefore,no.of revolutions it will make in covering 22 km(22000m)

=total distance covered/ C.S.A

=220000/44=5000.

hope this helps u

be happy

Answer 2

SOLUTION:-

Given:

The radius of a wheel of a bus is 0.70m.

Therefore,

We know that, circumference of the wheel is 2πr.

$= > 2 \times \frac{22}{7} \times 0.70 \\ \\ = > \frac{30.8}{7} \\ \\ = > 4.4m$

1km= 1000m

22km= 22× 1000m

=) 22000m

So,

Revolution take covering;

$= > \frac{22000}{4.4} \\ \\ = > 5000 \: round$

Hence,

5000 revolution covering in 22km.

Hope it helps ☺️
