Solids with specified cross-sections.

- Volume by Parallel Cross Sections; Discs and Washers - Practice with Volume by Parallel Cross Sections; Discs and Washers.

- How do you find the volume of a solid with cross-sectional area?
- How do you find the volume of a solid using integrals?
- How do you find the volume of a solid whose base is bounded by y = 1 - x^2?
- What is the volume differential?
- How can you derive the formula of a right circular cone using integrals?

This video is about the integration of cross-sectional area. Parts of this video are rather theoretical, although the images are really impressive and helpful. Some example problems of finding the volume of solids are shown. Some cross-sections are squares, while in other examples the cross-sections are semi-circles. This is a very useful and interesting video.
