How is a cylinder generated?
The height (or altitude) of a cylinder is the perpendicular distance between its bases. The cylinder obtained by rotating a line segment about a fixed line that it is parallel to is a cylinder of revolution . The height of a cylinder of revolution is the length of the generating line segment.
What is the value of a right circular cylinder?
The formula to find the volume of a right circular cylinder whose radius is r and height is h is, V = πr2h. i.e., the volume directly varies with the square of the radius, and also it directly varies with the height of the cylinder.
Why the cylinder is called right circular?
A right circular cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base. It is also called a right cylinder. The two circular bases of the right cylinder have the same radius and are parallel to each other.
What is the shape of cylinder?
A cylinder is a three-dimensional solid shape that consists of two parallel bases linked by a curved surface. These bases are like a circular disk in a shape. The line passing from the center or joining the centers of two circular bases is called the axis of the cylinder.
Why is it called a right circular cylinder?
Right Circular Cylinder Definition If the axis of the cylinder is perpendicular to its base then the cylinder is called a right circular cylinder. From the below figure segment AB is the axis of the cylinder it joins the centre of the two bases of the cylinder.
What is the definition of a right circular cylinder?
right circular cylinder. noun Geometry. a cylinder generated by the revolution of a rectangle about one of its sides.
How is a cylinder generated by a revolution?
a cylinder generated by the revolution of a rectangle about one of its sides.
When do you call a cylinder a cylinder?
If the bases are disks (regions whose boundary is a circle) the cylinder is called a circular cylinder. In some elementary treatments, a cylinder always means a circular cylinder. The height (or altitude) of a cylinder is the perpendicular distance between its bases.
How to calculate the surface area of a circular cylinder?
Total Surface Area of a Right Circular Cylinder. = Lateral Surface Area + 2 × (Area of the Cross Section) = 2πrh + 2πr 2. = 2πr(h + r) Solved Examples on Volume and Surface Area of Right Circular Cylinders: 1. The radius of the base of a solid right circular cylinder is 7 cm and its height is 20 cm.
