**1. What is a cylinder according to RD Sharma Solutions for Class 8 Maths - Mensuration III - Free PDF Download?**

A cylinder is a solid surface created by a line travelling parallel to a fixed-line, with its end describing a closed figure in a plane. A prism's limiting case is a cylinder. This old-fashioned viewpoint is still used in basic applications of geometry, but the unexpected numerical perspective has shifted to the infinite curved surface, which is how a cylinder is now defined in a few modern portions of geometry and topology. Terminology has been thrown into disarray as a result of the change in simple meaning.

**2. What are the parts of a cylinder mentioned in RD Sharma Solutions for Class 8 Maths - Mensuration III - Free PDF Download?**

Base and side The bases are all the same and run in the same direction. If you could 'unroll' the cylinder, you'd notice that the side is really a rectangular shape when straightened out.

Height The height h is the perpendicular distance between the two bases. When calculating the volume of a tilted cylinder, it is critical to utilize the perpendicular height ('altitude').

The radius r of a cylinder is equal to the radius of the base. If you're given the diameter rather than the length, make sure you split it in half.

Axis A line that links the centers of the two bases.

**3. What are Right, Oblique, and Hollow Cylinder mentioned in RD Sharma Solutions for Class 8 Maths - Mensuration III - Free PDF Download?**

The cylinder is termed a Right cylinder if a line is perpendicular to the base; otherwise, it is called an oblique cylinder. The axis of the cylinder is the line that connects the centers of the bases. A hollow cylinder is one that has a difference in radius between the internal and exterior radius and is empty on the inside. These are some basic differences between all these cylinders.

**4. What are some key elements to take away from RD Sharma Solutions for Class 8 Maths - Mensuration III - Free PDF Download?**

Some of the important points to remember are listed below.

The volume of a space (solid) area equals its magnitude.

The base of a right circular cylinder is the plane end of the cylinder.

The axis of a right circular cylinder is the line segment connecting the centers of the circular ends. The height of the cylinder is equal to the length of the axis.

The lateral surface of a right circular cylinder is the curved surface that connects the two bases.

**5. What are some properties of the right circular cylinder mentioned in RD Sharma Solutions for Class 8 Maths - Mensuration III - Free PDF Download?**

Some basic properties of a cylinder as listed below.

The axis is the line that connects the circle's centers.

A right cylinder is made by rotating a rectangle around one side as the axis of revolution.

The rectangle is the section generated by cutting a right circular cylinder with a plane that includes two components and runs parallel to the cylinder's axis.

It's a circle if a plane slices the right cylinder horizontally parallel to the bases.
