Question

A wheel makes 158 revolutions​

Answer 1

Step-by-step explanation:

Hey there !!

Given that ,

r = 35/2

circumference = 2πr

No. of revolution = 50

total Distance travelled by the wheel = 2πr ×50

=>$\begin{gathered}\sf 100 \times \frac{22}{7} \times \frac{35}{2} \\ \\ \sf = > 100 \times 11 \times 5\sf \\ = > 100 \times 55 \\ \sf = > 5500 \: cm \\ = > \frac{5500}{1000} \\ \sf = > 5.5 \: km\end{gathered}$

Hence the Distance travelled by the wheel is 5.5 km

Hope this helps u!!
