Answer
$ 6.632\times 10^{-4}\ m$
Work Step by Step
It is given:
initial temperature $T_1 = -16^{\circ} C$
final temperature $T_2 =32^{\circ} C$
initial diameter $L= 170\ in =170 \ in(\frac{2.54\ cm}{1\ in}) = 431.8\ cm$
Linear expansion coefficient$(\alpha)$ for pyrex glass is $3.2\times 10^{-6}/^{\circ} C$.
The change in diameter is given by;
$\Delta L =L\alpha(T_2-T_1)$
$\Delta L =(431.8\ cm)(3.2\times 10^{-6}/^{\circ} C)((32^{\circ} C-(-16^{\circ} C))$
$\Delta L = 0.06632\ cm$
$\Delta L = 6.632\times 10^{-4}\ m$
