First you need to know the formula for resistance, which is:

[tex]R=[/tex] ρ  [tex]\frac{L}{A} [/tex]    --- (A)

Where,
ρ = Resistivity 
L = length 
A = Area

ρ = Resistivity of tungsten = 5.28 x [tex]10^{-8}[/tex] Ωm
L = Length = 4.5 m
A = Area = 0.55 * [tex]10^{-3}[/tex] * π

Plug-in the values in equation(A), you would get:

[tex]Resistance = \frac{5.28 *10^{-8} * 4.5}{0.55 * 10^{-3} * \pi } [/tex]

[tex]Resistance = 1.375 * 10^{-4} [/tex]Ω
