Answer 1

I hope it helps. As per I Have solved it

Answer 2

Hey !!! ^_^

Here is your answer

⬇️⬇️⬇️⬇️⬇️⬇️⬇️

Given ..

No. of revolution = 1500

Distance covered by carriage

= 4.5 km

Convert km into m

then ,

4.5 × 1000 m

As we know ..

2πr × No. of revolution = Distance

So ,

2πr × 1500 = 4.5 × 1000

$2\pi \: r = \frac{4.5 \times 1000}{1500} \\ \\ 2\pi \: r = 3 \\ \\ r = \frac{3 \times 7}{2 \times 22} \\ \\ r = \frac{21}{44} \\ \\ r = 0.48 \: m \: (approx)$
So the radius is 0.48 m
