What else can I help you with?
Why aren't cylinders cones and spheres polyhedrons geometry?
polyhedrons need flat face and edges, corners which cylinder cones don't have.
Are not polyhedrons check all that apply.?
Polyhedrons are defined as three-dimensional shapes with flat polygonal faces, straight edges, and vertices. Therefore, objects that do not meet these criteria, such as spheres, cylinders, and cones, are not considered polyhedrons. Additionally, shapes with curved surfaces or those that are not fully enclosed do not qualify as polyhedrons.
Cylinders and cones are just polyhedrons with circular bases?
False. Cylinders and cones are not just polyhedrons with circular bases.
Why are cylinders and cones not considered to be polyhedrons?
Cylinders and cones are not considered polyhedrons because they do not have flat faces, which is a defining characteristic of polyhedrons. Polyhedrons are three-dimensional shapes made up of flat surfaces, while cylinders and cones have curved surfaces. Additionally, polyhedrons have straight edges where faces meet, whereas cylinders and cones have curved edges. Therefore, cylinders and cones are classified as curved surfaces rather than polyhedrons.
What is the name for a three dimensional shape?
These could be called solids.There are lots of three dimensional shapes. Cubes, spheres, cylinders, cones, toroids, pyramids, helixes, the various polyhedrons..
Are cones polyhedrons?
no because it has curved faces.
Cones and polyhedrons both have only one base?
false
How do you find the surface area of pyramids and cones and spheres?
you do stuff
Why aren't cylinders and cones and spheres polygons?
polygons have faces and cylinders and cone and spheres only has bases not faces.
How many cones fit into a cylinder?
That depends upon the relative sizes of the cones and the cylinder.
Is there a radius on a rectangular prism?
No, only on shapes with circles such as cones and spheres.
What is the similarity among spheres cones and cylinders?
A circular cross-section.
