# Funny Wire

Metal wire A is $100\text{ cm}$ long and has a diameter of $2 \text{ mm}$. Its resistance from end to end is $3.00\ \Omega$.

Metal wire B is also $100\text{ cm}$ long, but its diameter increases linearly from $1 \text{ mm}$ at one end to $3 \text{ mm}$ at the other end.

If the wires are made of the same material, what is the resistance of wire B (in $\Omega$)?
