FAQs on RD Sharma Class 8 Solutions Chapter 22 - Surface Area and Volume of Right Circular Cylinder (Ex 22.2) Exercise 22.2
1. How is the Right Circular Cylinder’s Volume calculated?
The volume of a right circular cylinder with radius r and height h equals V = πr2h, as we learnt in the previous section. As a result, we'll use the procedures below to calculate the volume of the right circular cylinder.
Step 1: Determine the radius and give it the letter r; determine the height and give it the letter h.
Step 2: Using the formula V = πr2h, calculate the volume.
Step 3: Use cubic units to represent the final answer.
2. What Is the distinction between a Cylinder and a Right Circular Cylinder?
There are many distinctions between a cylinder and a right circular cylinder. The main difference that distinguishes between a cylinder and a right circular cylinder is stated below:
An oblique cylinder or a right circular cylinder are two types of cylinders. The bases of a right circular cylinder are parallel and congruent circles, with each lateral curved surface line segment perpendicular to the bases. A cylinder that is not a right circular cylinder is known as an oblique cylinder.
3. What are the characteristics of the Right Circular Cylinders?
A right circular cylinder has the following properties:
A right circular cylinder has two curved edges, one curved surface, and two flat faces.
The bases are always in sync with one another.
The size of the cylinder can be determined by the radius of the base and the height of the cylinder.
The axis is at a right angle to the bases and crosses them perfectly.
There isn't a vertex or a corner on it.
The cylinder's base and top are always similar to one another.
4. Write a few differences between the Total Surface Area and Curved Surface Area of the Right Circular Cylinder.
The area occupied by the full right circular cylinder is defined as the total surface area of the cylinder. By combining the areas of two circles and a curved surface, this area is determined. The formula 2r(h+r) square units are used to compute the total surface area of a right circular cylinder.
The right circular cylinder's curved surface area is defined as the area occupied by the curved surface of the right cylinder. The formula 2rh square units is used to compute the curved surface area of a right circular cylinder.
5. How do you define a Cylinder’s area?
The total area covered by a cylinder in three-dimensional space is called the cylinder's area. The area of a cylinder is equal to the sum of the areas of two circular bases plus the area of a curved surface. The two circular bases of the right cylinders are perfectly over each other, and the axis line forms a right angle to the base. The oblique cylinder is formed when one of the circular bases is moved and the axis does not generate a right angle to the base.
