Finding area of rectangular solids and cylinders by cutting them into flat pieces and adding the areas.
This geometry lesson shows how to find the volume and surface area of a cylinder. [Geometry playlist: Lesson 20 of 31]
The students will review solid figures using a baggie of assorted snack mix (cones, cubes, cylinders, and spheres) and will begin a vertical bar graph showing the number of each solid figure in a bag of assorted snack mix.
An interactive applet and associated web page that demonstrate the volume of a cylinder. A cylinder is shown where the height and radius can both be changed by dragging. The volume is continuously recalculated as you drag. The calculations can be turned off for class discussion. The web page has the formula for the volume calculation, and a discussion about the subtle distinction between the volume of a cylinder and the volume inside the cylinder. The web page also has links to other pages defining the various properties of an ellipse and to some ellipse constructions. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
Се воведува n-димензионален простор и поим за функција во него. Посебно се проучува 3-димензионалниот простор и графички се прикажуваат елементарните површини во простор. Се дефинира граница и непрекинатост на функција од две независни променливи.
The n-dimensional space and specially, 3-dimensional space is introduced. The most common surfaces in 3-dimensional space are shown. The definitions of a limit and continuity are given.
