A capillary tube has the shape of a cylinder, so its volume can be determined using the formula for a cylinder's volume, [tex][tex]$V=\pi r^2 h$[/tex][/tex]. You will measure the height, [tex][tex]$h$[/tex][/tex], later. To find the radius, measure the diameter with a pair of calipers or a ruler and divide by 2. Record your answer to the nearest [tex][tex]$0.1 cm$[/tex][/tex].

To find the radius of the capillary tube, follow these steps:

1. Measure the Diameter: Use a pair of calipers or a ruler to measure the diameter of the capillary tube. Let's say the measurement you obtain is [tex]\(0.0\)[/tex] cm.

2. Calculate the Radius: The radius is half the diameter. Given that the diameter is [tex]\(0.0\)[/tex] cm,
[tex]\[ \text{Radius} = \frac{\text{Diameter}}{2} = \frac{0.0 \, \text{cm}}{2} = 0.0 \, \text{cm} \][/tex]

3. Record the Radius: Since the problem asks you to record your answer to the nearest 0.1 cm, we note that the radius is already [tex]\(0.0\)[/tex] cm, and it does not need further rounding.

Therefore, the radius of the capillary tube is [tex]\(0.0\)[/tex] cm when recorded to the nearest 0.1 cm.

So, we can fill in the blank in the table as follows:
[tex]\[ \text{Radius: } 0.0 \, \text{cm} \][/tex]
