Which of the following best describes a cone?
A. A three-dimensional solid made from two parallel and congruent discs not in the same plane and all the points between them
B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex
C. A three-dimensional solid consisting of a base, a point not in the same plane as the base, and all the points between them
D. A three-dimensional solid consisting of two parallel congruent polygons and all the points between them

Respuesta :

Option B: A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex

The A is a cylinder, the D es pyramid, and I cannot figure out what the C is.

A cone is best described in the point:

B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex.

What are three-dimensional figures?

Three-dimensional figures are solid shapes, having three dimensions: length, width, and height.

Some examples of three-dimensional figures are cube, cuboid, cone, and cylinder.

How do we solve the given question?

We will discuss the description of all the figures given to us, try to know which figure is the description about, and then will tell what is the description of a cone.

A. A three-dimensional solid made from two parallel and congruent discs not in the same plane and all the points between them.

- The description is of a cylinder. A cylinder has both its end as two parallel and congruent discs, which are not on the same plane and include all the points between the discs.

B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex.

- The description is of a cone. A cone has a circular base, which grows smaller and smaller to a point.

C. A three-dimensional solid consisting of a base, a point not in the same plane as the base, and all the points between them.

- The description is of a pyramid. A pyramid can have any base, that grows smaller and smaller to a point.

D. A three-dimensional solid consisting of two parallel congruent polygons and all the points between them.

- The description is of a prism. On either end of a prism are two polygonal forms that can be any shape with three or more sides.

∴ A cone is best described in the point:

B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex.
