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