The variation of applied potential and current flowing through a given wire is shown in figure. The length of wire is $\displaystyle 31.4$ cm. The diameter of wire is measured as $\displaystyle 2.4$ cm. The resistivity of the given wire is measured as $\displaystyle x \times 10^{-3} \Omega \mathrm{~cm}$. The value of $\displaystyle x$ is \_\_\_\_.
[Take $\displaystyle \pi=3.14$ ]
