Answer :
To determine the radius of the capillary tube, follow these steps:
1. Measure the Diameter: Start by measuring the diameter of the capillary tube using a pair of calipers or a ruler. For this example, let's assume you measured the diameter to be 3.0 cm.
2. Calculate the Radius: The radius [tex]\( r \)[/tex] of a cylinder is half of its diameter. This can be computed using the formula:
[tex]\[ r = \frac{\text{diameter}}{2} \][/tex]
Substituting the given diameter of 3.0 cm:
[tex]\[ r = \frac{3.0 \text{ cm}}{2} = 1.5 \text{ cm} \][/tex]
3. Round to the Nearest 0.1 cm: The calculated radius is already 1.5 cm, which is to the nearest 0.1 cm.
So, the radius of the capillary tube is:
[tex]\[ \boxed{1.5} \text{ cm} \][/tex]
