What is the radius of a circle in relation to its diameter?

The radius of a circle is defined as the distance from the center of the circle to any point on its circumference. The diameter, on the other hand, is the distance across the circle through its center, effectively spanning from one edge of the circle to the other.

The relationship between the radius and the diameter is straightforward: the radius is always half of the diameter. This means that if you take the diameter of a circle and divide it by two, you will obtain the length of the radius. This fundamental relationship underpins much of the geometry related to circles.

Thus, asserting that the radius is one-half of the diameter correctly captures this essential geometric principle.
