A representative disc is a three-dimensional volume element of a solid of revolution. The element is created by rotating a line segment (of length w) around some axis (located r units away), so that a cylindrical volume of πr2w units is enclosed.
How do you find the volume of a solid rotation around the Y axis?
Answer: The volume of a solid rotated about the y-axis can be calculated by V = π∫dc[f(y)]2dy. Let us go through the explanation to understand better. The disk method is predominantly used when we rotate any particular curve around the x or y-axis.
What is meant by solid of revolution?
Definition of solid of revolution : a mathematical solid conceived as formed by the revolution of a plane figure about an axis in its plane.
What are right solids and oblique solids?
Explanation: Right solid : A solid geometrical figure whose axis (or lateral edges) is perpendicular to its base. Oblique Solid : An oblique solid has base(s) that is (are) not perpendicular to the lateral edges.
What is the use of solids of revolution?
A solid of revolution is a volume obtained by rotating a planar arc around the axis of revolution that lies on the same plane. The disk method is used to calculate the volume of a solid of revolution when integrating along an axis parallel to the axis of revolution.
What are the characteristics of a solid it has a?
Explanation: A solid has a definite volume and fixed shape. This is in contrast to a liquid, which has a definite volume, but takes the shape of its container and has a flat surface.
What are oblique solids?
oblique solid. oblique solid. An oblique solid has base(s) that is (are) not perpendicular to the lateral edges. Related Term: right solid.

What are the properties of the group 18 elements?
Table 18.14.1: Selected Properties of the Group 18 Elements Property Helium Neon Argon Xenon atomic symbol He Ne Ar Xe atomic number 2 10 18 54 atomic mass (amu) 4.00 20.18 39.95 131.29
What are the valence electron configurations of Group 18 elements?
The elements of group 18 all have closed-shell valence electron configurations, either ns 2 np 6 or 1s 2 for He. Consistent with periodic trends in atomic properties, these elements have high ionization energies that decrease smoothly down the group.
How to find the volume of the solid generated by revolving?
Example 1: Find the volume of the solid generated by revolving the region bounded by y = x 2 and the x ‐axis on [−2,3] about the x ‐axis. Because the x ‐axis is a boundary of the region, you can use the disk method (see Figure 1 ). Figure 1 Diagram for Example 1.
