A one meter section of circular cross-section wire has a resistance of 382 Ohms. If you stretched the wire (while maintaining a circular cross-section), how long would the wire have to be to have a resistance that is 48.8 times as large? Don't round. The answer should be 6.99 but I need steps to understand the answer.

The resistance R of a wire of length l and uniform area of cross-section A is given by R = rhol/A, where rho is the resistivity of the wire. You melt the wire and recast it to have a new length l' = 10l (keeping the volume V = Al of the wire constant). What is the new resistance of the wire, if the original resistance of the wire was 100.0 Ohm.

A wire of length L and cross-sectional area A has resistance R. What will be the resistance Rstretched of the wire if it is stretched to twice its original length? Assume that the density and resistivity of the material do not change when the wire is stretched.
