Question

which model shows the diameter?

Explanation:

Step1: Recall the definition of diameter

The diameter of a circle is a straight line passing through the center and connecting two points on the circle.

Step2: Analyze each model

• In the first model, the line does not pass through the center.
• In the second model, the line passes through the center and connects two points on the circle.
• In the third model, the line is a radius (connects the center to a point on the circle, not two points through the center).

Answer:

The second model.
