Answer 2

The number of rounds that a wheel of diameter 7/11 m will make in going 4 km, is 2000

Step-by-step explanation:

Diameter of wheel = $\frac{7}{11}m$

Radius of wheel = $\frac{\frac{7}{11}}{2}=\frac{7}{22}m$

Circumference of wheel = $2\pi r = 2 \times \frac{22}{7} \times \frac{7}{22}=2 m$

So, No. of rounds covered in 2 m = 1

1 km = 1000 m

4 km= 4000 m

No. of rounds covered in 4000 m = $\frac{1}{2} \times 4000 = 2000$

Hence The number of rounds that a wheel of diameter 7/11 m will make in going 4 km, is 2000
