Question

the diameter of a bicycle wheel is 28cm.

• what distance will it cover in 100 revolutions.
• how many revolutions will it make to travel 352m.

Answer 1

Dear student,

$$\begin{gathered} \left(i\right)1revolutionofwheel=circumferenceofwheel \\ 100rev\left(dis\tan ce\right)=100\times 2\times \frac{22}{7}\times 14=88cm\times 100=8800cm \\ \left(ii\right)no.ofrevolution=\frac{dis\tan ce}{circumferenceofwheel}=\frac{352}{88}=4 \end{gathered}$$
