Question

select the correct answer from each drop - down menu.
point a is the center of this circle.
the ratio of the lengths of to is 2:1.

Explanation:

Step1: Recall the properties of radius and diameter

In a circle, the diameter \(d = 2r\), where \(r\) is the radius.

Step2: Analyze the line - segments

If we consider a diameter (e.g., \(CI\)) and a radius (e.g., \(AF\)). The length of a diameter is twice the length of a radius.

Answer:

The ratio of the lengths of \(CI\) (diameter) to \(AF\) (radius) is \(2:1\)
