A cone is a solid made from a disc, a point not in the same plane as the disc, and all points between them.A.TrueB.False

Analysis of the Statement

1. Understanding the Definition of a Cone: A cone is defined as a three-dimensional shape that has a circular base and a single vertex (or apex) that is not in the same plane as the base. The surface of the cone is formed from line segments that connect every point on the circular base to the apex.

2. Breaking Down the Components:

   • A disc refers to the circular base of the cone.
   • The point not in the same plane as the disc is the apex of the cone.
   • The points between the disc and apex refer to the area of the cone itself, which extends from the circular base to the apex.

Conclusion

Given that all components of the definition match the elements described in the statement, it is indeed true that a cone is formed in the way described.

Final Answer

The statement is A. True.
