Question

which figure is described below? all points in space 4 units from a point. circle 2 lines sphere

Explanation:

Step1: Analyze the description

The problem describes all points in space that are 4 units from a single point.

Step2: Recall geometric definitions

• A circle is defined as all points in a plane at a fixed distance from a point (the center), so it's a 2 - dimensional figure.
• Two lines with a point 4 units from each line don't match the description of all points at a fixed distance from a single point.
• A sphere is defined as all points in space at a fixed distance (the radius) from a point (the center). Since the description specifies "in space", the figure must be a sphere.

Answer:

Sphere
