Many solid objects, especially those made on a lathe , have a circular cross-section and curved sides. On this page, we see how to find the volume of such objects using integration.

For each of the following problems use the method of cylinders to determine the volume of the solid obtained by rotating the region bounded by the given curves about the given axis. Practice Quick Nav Download. You appear to be on a device with a "narrow" screen width i. Due to the nature of the mathematics on this site it is best views in landscape mode.

Appropriate Integrals

Often a given problem can be solved in more than one way. A particular method may be chosen out of convenience, personal preference, or perhaps necessity. Ultimately, it is good to have options. The previous section introduced the Disk and Washer Methods , which computed the volume of solids of revolution by integrating the cross--sectional area of the solid. This section develops another method of computing volume, the Shell Method.

This section contains documents created from scanned original files, which are inaccessible to screen reader software. A " " symbol is used to denote such documents. Method for finding the area between two curves. Introduces the disk method with worked examples of finding the volume of a right circular cone and a sphere. Variation of disk method using the difference of two disks to create washers.

6.3: Volumes of Revolution: The Shell Method

In this section, we examine the method of cylindrical shells, the final method for finding the volume of a solid of revolution. We can use this method on the same kinds of solids as the disk method or the washer method; however, with the disk and washer methods, we integrate along the coordinate axis parallel to the axis of revolution. With the method of cylindrical shells, we integrate along the coordinate axis perpendicular to the axis of revolution. The ability to choose which variable of integration we want to use can be a significant advantage with more complicated functions. Also, the specific geometry of the solid sometimes makes the method of using cylindrical shells more appealing than using the washer method. In the last part of this section, we review all the methods for finding volume that we have studied and lay out some guidelines to help you determine which method to use in a given situation. Again, we are working with a solid of revolution.

We strongly recommend that the reader always first attempts to solve a problem on his own and only then look at the solution here. Area between curves Opens a modal Composite area between curves Opens a modal … Definite integrals can be used to determine the mass of an object if its density function is known. Problem: Evaluate the integral Problem: Evaluate the … In the upcoming discussion let us discuss few important formulae and their applications in determining the integral value of other functions. Application Integration Approaches As we've come to appreciate, application integration is a combination of problems. In the discussion of the applications of the derivative, note that the derivative of a distance function represents instantaneous velocity and that the derivative of the velocity function represents instantaneous acceleration at a particular time. Chapter 7 — Applications of Integration 3 Notice that this width w h could vary as the depth changes, depending on the shape of the wall.

Даже в такие моменты ему удавалось сохранять ясность рассудка. - А вы не думали о том, чтобы позвонить президенту. Стратмор кивнул: - Думал. Но решил этого не делать. Сьюзан так и подумала.

Разница между критическими массами. Семьдесят четыре и восемь десятых. - Подождите, - сказала Сьюзан, заглядывая через плечо Соши.  - Есть еще кое-что. Атомный вес. Количество нейтронов. Техника извлечения.

 - Бринкерхофф рассеянно кивнул, стараясь не смотреть на лиф ее платья. - Когда знаменатель равняется нулю, - объясняла Мидж, - результат уходит в бесконечность. Компьютеры терпеть не могут бесконечности, поэтому выдают девятки.  - Она показала ему другую колонку.  - Видишь. - Вижу, - сказал Бринкерхофф, стараясь сосредоточиться на документе.

Как и многие другие сотрудники АНБ, он использовал разработанную агентством программу Мозговой штурм - безопасный способ разыгрывать сценарий типа Что, если?. на защищенном от проникновения компьютере. Мозговой штурм был своего рода разведывательным экспериментом, который его создатели называли Симулятором причин и следствий.
