An air-filled cylinder with a moveable piston has a long tube attached to it which connects to a pressure sensor. The volume of the cylinder is initially $30.0 \text{ mL}$, and the absolute pressure is equal to $101{,}000 \text{ Pa}$.

The piston slowly compresses the air until the new volume of the cylinder is $15.0\text{ mL}$, half of the initial volume. However, the new pressure is only $196{,}000\text{ Pa}$. All measurements are taken at room temperature.

Calculate the volume inside the tube that connects the cylinder to the pressure sensor.


$1.6\text{ mL}$


$0.74\text{ mL}$


$0.95\text{ mL}$


Dimensions of the tube must be given to calculate its volume.
