What is the relationship between the radius of a circle and the diameter of a circle?
A. The diameter is twice the length of the radius.
B. The radius is half the length of the diameter.
C. The radius is a segment whose endpoints are the center of the circle and a point on the circle. The diameter is a chord that passes through the center of the circle, but whose endpoints are points on the circle.
D. All of the above

this is a basic fact of geometry, musa, and ideally you'd know this info from having read your textbook and/or online course materials.  

Or you could do an Internet search.  Use the Google search engine:  type in "radius and diameter" and see what that gives you.  The relationship between diameter and radius is a very simple one.
