The resistance of a wire is given by the expression
$$R=\frac{4\rho L}{\pi D^2},$$
where, $\rho$ is the resistivity ($\Omega$-meter), $L$ is the length (meter) and D (meter) is the diameter of the wire. The error in measurement of each of the parameters $\rho,L,$ and $D$ is $\pm 1.0\%$. Assuming that the errors are independent random variables, the percent error in measurement of $R$ is __________.
