$\huge \underbrace \mathfrak \red{\bigstar Explanation}$

As we know that :

$\tt \pink{\boxed{In \:1 rotation,\: wheel\: travel\: a\: distance\: = \:circumference}}$

$\begin{gathered}\pink\bigstar\:\bigg\{\:\bf\blue{Radius\:(r)=\:28cm\: ,Distance \: travel \: = 352m (35200cm)}\:\bigg\}\:\pink\bigstar \\ \end{gathered}$

Therefore ,

$\mathbb { Number \: of \: rotation \: =\huge{ \frac{Distance \: travel }{Circumference \: of \: circle} }}$

$\mathfrak{\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=\large{ \frac {35200cm }{2πr }}}$

$\mathfrak{\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=\large{ \frac {35200cm }{2×\frac{22}{7}×28 }}}$

$\mathfrak{\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:= \large{\frac {\cancel{35200}}{\cancel2×\frac{\cancel{22}}{\cancel7}×\cancel{28 }}}}$

$\mathfrak{\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:=\large{ 200\: Times \: Ans}}$

Answer 2

$given \: - \\ r = 28cm \: and \: \\ distance \: travel \: = \: 352m \: \\ \\ m \: --> cm \\ 1m = 100cm \\ 352m = 352 \times 100 \\ = 35200cm.$

$we \: know \: - \\ number \: of \: rotations \: = \frac{distance \: travel \: }{circumference \: of \: circle \: }$

$= \frac{35200cm}{2\pi r}$

$= \frac{35200cm}{2 \times \frac{22}{7} \times 28}$

$= \: 200 \: times$

Answer — 200 times
