Question

the diameter of wheel of bus is 90 cm .in how many revolution wheel of bus will cover distance of 14.13 km

Answer 1

have to cover 14.13*1000*100 cm
1413000 cm

circumference of wheel = 1 revolution
2pie r
2*22/7*45
282.85

1413000/282.85
4996 revolution

Answer 2

5000 revolution wheel of bus will cover distance of 14.13 km

Step-by-step explanation:

Diameter of wheel = 90 cm

Radius of wheel = $\frac{90}{2}=45 cm$

Circumference of wheel = $2 \pi r = 2 \times 3.14 \times 45=282.6 cm$

1 km = 100000 cm

282.6 cm =$\frac{282.6}{100000}=0.002826 km$

So, Distance traveled in 1 revolution = 0.002826 km

No. of revolution in 1 km =$\frac{1}{0.002826}$

No. of revolution in 14.13 km =$\frac{1}{0.002826} \times 14.13=5000$

Hence 5000 revolution wheel of bus will cover distance of 14.13 km
