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.

Problem 19.72 (Multistep) A bent bar A 43 cm long high-resistance wire with rectangular cross section 7 mm by 3 mm is connected to a 12 volt battery through an ammeter, as shown in the figure. The resistance of the wire is 58 ohms. The resistance of the ammeter and the internal resistance of the battery can be considered to be negligibly small compared to the resistance of the wire. Leads to a high-resistance...

You need to prepare a 0.133-mm-diameter tungsten wire with a resistance of 3.03 kΩ. How long must the wire be? The resistivity of tungsten is 5.62 × 10-8 Ω·m. I keep coming up with an extremely large number, however I don't think that's correct.
