What is the relationship between the radius and the diameter?
![Page 12: Circle Terminology. Circle The set of points in a plane that are a fixed distance from a given point called the center of the circle](https://reader035.vdocuments.mx/reader035/viewer/2022062401/5a4d1af97f8b9ab059983109/html5/thumbnails/12.jpg)
If you said:
The diameter is twice the radius.
The radius is half of the diameter.
You are absolutely correct.
