Answer 1

Answer:

Step-by-step explanation:

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 =$\frac{7}{11 \times 2}=\frac{7}{22} m$

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

No. of rounds completed in 2 m = 1

No. of rounds completed in 1 m =$\frac{1}{2} m$

No. of rounds completed in 4 km(= 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
