A cylinder is like a can and a sphere is like a ball.
polyhedrons need flat face and edges, corners which cylinder cones don't have.
A sphere is like a 3D circle . A cylinder has one curved side and two circular ones. Sphere...............................................baseball Cylinder............................................soda can
Cylinder (body, legs, tails) Spheres (eyes) triangles (ears and hooves)
polyhedrons need flat face and edges, corners which cylinder cones don't have.
Spheres and cylinders are studied in geometry. In fact there is a geometry that just deals with spheres called spherical geometry. Imagine living on a sphere ( you almost do) compared to living on a plane. Some geometric postulates must be modified for this.There is a geometry of living on the surface of a cylinder too.
The cross section of a sphere is most often a circle. When the cross section is taken parallel to the base of a cylinder, it is also a circle.
I assume this is true or false... since it is only a statement and not a question. True
Archimedes. Archimedes published a work named "On the Sphere and Cylinder", where he proved the formulas for the surface area and volume of both spheres and cylinders. This is actually quite impressive, considering that he lacked the concept of calculus or limits to aid him. In calculus, the proof for the volume of a cylinder because trivial through integration by slicing.
Spheres
Stratosphere, mesosphere, and thermosphere . :)
Galatea of the Spheres was created in 1952.
Spheres of Chaos was created in 2000.
