Question

The wheel of a bullock cart has a diameter of 1.4m. How many rotations will the
wheel complete as the cart travels 1.1 km ?​

Answer 1

Answer:

250 rotation

Step-by-step explanation:

diameter=1.4m

radius=0.7or7/10

we know that

1km=1000m

so,1.1km=1.1*1000m=1100m

NO.OF ROTATION=. TOTAL DISTANCE GIVEN

CIRCUMFERENCE

=1100/2π

=1100/2*22/7*7/10

=1100*7*10/22*4

=11000/44

=250

there fore no.of time the wheel has tk rotate is 250 times to cover 1.1km

Answer 2

Solution :

It is given that the wheels of a certain bullock cart has a diameter of 1.4 m or 140 cm.

Now, the radius of the wheels become 70 cm .

Circumference of the wheel :

> 2 pi r

> 2 * 22/7 * 70

> 2 * 22 * 10

> 22 * 20

> 440 cm.

Now, the cart travels a distance of 1.1 km or 110000 cm .

The number of revolutions made by the wheel to cover this distance is 250 revolutions.

This is the required answer.
