Question

which statement about the radius of a sphere is true? the radius is a three - dimensional circle in which all points are equidistant from a fixed point. the radius is a line segment from the center point to the surface of the sphere. the radius is a chord from one point on the surface of the sphere to another point on the surface of the sphere. the radius is created from a plane that passes through the center of the sphere.

Explanation:

• A sphere's radius is defined as a line segment from the center to the surface.
• A three - dimensional circle with all points equidistant from a fixed point describes the sphere itself, not the radius.
• A chord is a line segment between two points on the surface, which is not the radius.
• A plane passing through the center creates a great circle, not the radius.

Answer:

The radius is a line segment from the center point to the surface of the sphere.
