How to solve this question 

**Problem Statement:**

How long, \( L \), is a tungsten wire if it has a diameter of \( 0.173 \times 10^{-3} \) m and a resistance of \( 2.77 \, \text{k}\Omega \)? The resistivity of tungsten is \( 5.62 \times 10^{-8} \, \Omega \cdot \text{m} \).

**Equation to Solve:**

\[ L = \, \text{(to be completed by the user)} \]

**Units of Measurement:**

- \( L \): Length in meters (m)

**Additional Information:**

This problem is typically solved using the formula for the resistance of a wire:

\[ R = \rho \frac{L}{A} \]

Where:
- \( R \) is the resistance,
- \( \rho \) is the resistivity,
- \( L \) is the length,
- \( A \) is the cross-sectional area of the wire.

Use the formula to find the wire's length by rearranging it to solve for \( L \). Substitute known values once the cross-sectional area is calculated using the diameter of the wire.
