Which of the following correctly describes a sphere? (1 point)

Question

• A sphere has a face.
• A sphere has an edge.
• A sphere has a center.
• A sphere has a vertex.

Answer 1

The correct description of a sphere from the options provided is:

• A sphere has a center.

A sphere is a three-dimensional object where every point on its surface is equidistant from the center. It does not have faces, edges, or vertices.

Answer 2

Which of the following is true about the diameter of a sphere?
• The diameter is the shortest length on a sphere.
• The diameter is not a chord.
• The diameter of a sphere passes through the center of the circle.
• The diameter is 2.5 times the length of the radius.

Answer 3

The accurate statement about the diameter of a sphere from the given options is:

• The diameter of a sphere passes through the center of the circle.

• The diameter is not the shortest length (that would be the radius).
• The diameter is, in fact, a type of chord in a circle (or sphere) that passes through the center.
• The diameter is always twice the length of the radius, not 2.5 times.

So, the only correct statement is that the diameter passes through the center of the sphere (and the center of the circle, since a sphere is the 3D counterpart of a circle).
