Why dont cylinders cones and spheres have any edges?
The question is based on a false premise, and so cannot be answered.
Why are cylinders and cones not considered to be a polyh?
Polyhedra are 3-dimensional shapes bounded by polygons. Polygons are flat [plane] shapes bounded by straight lines. So a polyhedron cannot have any curved faces.
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..
How do you find the surface area of pyramids and cones and spheres?
you do stuff
What is the equation for area in math?
The formula depends on what shape you're working with. Triangles, circles, parallelograms, squares, trapezoids, ellipses, hexagons, prisms, cones, spheres, cylinders, etc. all have different formulas for their areas.
What is the similarity among spheres cones and cylinders?
A circular cross-section.
Why aren't cylinders cones and spheres polyhedrons geometry?
polyhedrons need flat face and edges, corners which cylinder cones don't have.
Which soilds have no perpendicular faces?
Spheres, cones and cylinders have no perpendicular faces that meet each other at right angles.
Why dont cylinders cones and spheres have any edges?

What is the difference between cones and cylinders and spheres?
sphere has 1 face and no vertex and it rolls but cone has 2 faces and it can roll and it has 1 vertex

What are 20 geometric shapes in nature?
The sun moon and other planets are spheres. Pine trees are cones. Tornadoes are upside down cones. The trunks of some trees and the stems of some plants are cylinders.
Is a three dimensional figures always a cube?
Yes, except for all the spheres, pyramids, cones, rectangular boxes, egg shapes, cylinders, etc.
What 3d shape has more than 1 vertex?
Most of them. Cubes, prisms, pyramids, and all the -hedrons. Roundish things, like cones, spheres, hemispheres and cylinders don't have them.

Cylinders and cones are just polyhedrons with circular bases?
False. Cylinders and cones are not just polyhedrons with circular bases.
