It should be noted that when there are two secant segments that intersect each other in a circle, the product of a segment is equal to that of the other segment.
<h3>What is a segment? </h3>
Your information is incomplete. Therefore, an overview of the relationship in a circle will be given. A segment is the set of points that has two end points.
There are two segments that can cross your circle which are the secant segment and the tangent segment.
Another relationship is that according to intersecting chord theorem, when two chords intersect inside a circle, the length of ab will be equal to cd.

The mass of the gold nugget is 71.22 g.
<h3>What is mass?</h3>
This can be defined as the quantity of matter a body contains. The S.I unit of mass is kilogram (kg)
To calculate the mass of the gold, we use the formula below.
Formula:
- m = Dv.............. Equation 1
Where:
- D = Density of the gold
- m = mass of the gold
- v = volume of the gold
From the question,
Given:
- D = 19.3 g/cm³
- v = 0.00369 L
To convert v from L to cm³, we multiply by 1000.
Therefore,
- v = (0.00369×1000) = 3.69 cm³
Substitute these values into equation 1
- m = 19.3×3.69
- m = 71.217 g
- m ≈ 71.22 g
Hence, The mass of the gold nugget is 71.22 g
