A voltmeter connected across the terminals of a tungsten$-$filament light bulb measures $116$ V when an ammeter in line with the bulb registers a current of $0\mathrm{.}647$ A $.$

$($a$)$ Find the resistance of the light bulb. $($Enter your answer in ohms.$)$

$$

$($b$)$ Find the resistivity of tungsten $($in $*m)$ at the bulb's operating temperature if the filament has an uncoiled length of $0\mathrm{.}573$ m and a radius of $2\mathrm{.}58{10}^{-5}m.$
