Answer 1

$$\begin{gathered} \mathrm{Distance}: \\ \mathrm{d}=1.5\times 2\mathrm{\pi r} \\ =1.5\times 2\times \mathrm{\pi }\times 2 \\ \mathbf{}\mathbf{=}\mathbf{18}\mathbf{.}\mathbf{8}\mathbf{}\mathbf{m} \\ \mathrm{Displacement}: \\ \mathrm{d}=\mathrm{Diameter}\mathrm{of}\mathrm{circle} \\ =2\mathrm{r} \\ =2\times 2 \\ \mathbf{}\mathbf{}\mathbf{=}\mathbf{4}\mathbf{}\mathbf{m} \end{gathered}$$
