Here is the circle diagram that includes the specified elements: 3 radii, 1 diameter, 4 chords, 2 secants, and 1 tangent. Each element is represented clearly within the circle.

Would you like further details on any part of the diagram, or do you have any questions?

Here are some related questions to expand on the topic:

1. What is the relationship between a tangent and a radius at the point of contact?
2. How does a chord differ from a secant geometrically?
3. Can a diameter also be considered a chord?
4. What are the properties of a circle that make secants and tangents behave differently?
5. How can you calculate the length of a chord given the radius and the distance from the center?

Tip: The perpendicular distance from the center of a circle to a chord is the key to calculating the length of the chord using basic geometry or trigonometry.
