Answer 1

The relationship between the radius and diameter of a circle is that the diameter is twice the radius.

Step-by-step explanation:

The relationship between the radius and diameter of a circle is that the diameter is twice the radius. The radius is the distance from the center of the circle to any point on its circumference, while the diameter is a straight line passing through the center and touching two points on the circumference. Therefore, if the radius is given, you can find the diameter by multiplying the radius by 2.
