Question

a carriage wheel makes 1500 revolution in going over a distance of 4.5 km find its radius taking Pi 3.14

Answer 1

Answer:

0.47 m

Step-by-step explanation:

Distance traveled in 1500 revolutions = 4.5 km

Distance traveled in 1 revolution = $\frac{4.5}{1500}$

                                                       = $0.003$

Circumference of wheel = $2\pi \times r$

Since the distance travel in 1 revolution = 0.003 km

So, circumference = 0.003 km                                      

So,$0.003=2\pi \times r$

$\frac{0.003}{2\times 3.14}=r$

$0.00047770=r$

1km = 1000 m

So,0.00047770 km = 0.47 m

Hence the radius is 0.47 m
