We are asked to find the diameter of the circle if CF is 14 inches long. Let's recall the definitions of radius and diameter.
Radius: Distance from the center of the circle to any point on the circumference.
Diameter: Distance from one side of the circle's circumference, through the center of the circle, to the opposite side.
Now let's consider the diagram.
We can see in the diagram that CF is a radius of the circle, and we are given that CF = 14 inches. According to the definitions, the diameter of a circle is twice the radius. Therefore, the diameter is 14* 2=28 inches.
