Développement du cylindre Hilbert and Cohn-Vossen wrote about the cylinder: "The circular cylinder is the simplest curved surface. It can be obtained from the simplest curves -the straight line and the circle- by moving a straight line around the circunference of a circle while keeping it perpendicular to the plane of the circle. Another way to get the cylinder is by rotating a straight line about an axis parallel to it. Thus the circular cylinder is a surface of revolution. The surfaces of revolution are an important class of surfaces, characterized by the property that they can be generated by rotating a plane curve about an axis lying in the plane of the curve." In this page, the cylinder will be closed by two parallel planes perpendicular to the axis. The main interest of this page is to see how a cylinder can be developed into a plane. The lateral surface area of a cylinder is the area of a rectangle. Do you remember how to calculate the volume of a cylinder?

Against All Odds: Inside Statistics 1. What Is Statistics? Statistics is the art and science of gathering, organizing, analyzing and drawing conclusions from data. And without rudimentary knowledge of how it works, people can't make informed judgments and evaluations of a wide variety of things encountered in daily life. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32.
RWM103: Geometry Making sure that objects are of equal size is important in life. Whether pieces of furniture, automobiles, or just pieces of a candy bar shared between siblings, we often have to make sure objects are the same size and shape. Have you ever had to prove something to a child? In this unit, you will also learn more about triangles and their various parts. We can also use triangles to map things out. If you live in a house, triangles are right over your heads. Completing this unit should take you approximately 18 hours.
