Answer:

Given ⇒

diameter = 56cm

radius = 56/2 = 28cm

distance = 1.56 km

circumference of circle = 2πr = 2 *π*28 = 56*22/7= 176

total rotations = 156000/ 176 = 886.14

ur answer is 886 rotations

hope it helps u

ANSWER-

We have,

Diameter of car wheel =56cm.

Radius = d/2 = 56/2 =28cm.

to convert 28cm to m,

r= 28/100m

=0.28m.

to convert 0.28m to km,

r= 0.28/1000

=0.00028km.

Now,

Circumference of the wheel in km/s =2πr

circumference=2×3.14×0.00028

circumference=0.0017584km

therefore,

Distance to the cover =1.056km.

Now, number of revolutions= 0.0017584/1.056

=600.40

≈600...... ans

Hence, this is the answer.
