The volume of a cylinder with a height of 8cm and radius of 3cm would be 226.19467 m3
To work out the volume of a cylinder, multiply one half of the diameter (this is known as the radius) by itself and then multiply by Pi to find the area. Then multiply the area by the length of the cylinder.
In the above case the calculation would look like this:
Radius x Radius ( 3 x 3 ) = 9
Answer x Pi ( 9 x 3.14159265 ) = 28. 27433385
Answer x Length ( 28. 27433385 x 8 ) = 226.19467
Another example would be: You have a cylinder that is six inches wide and eight inches long. Multiply one-half of the diameter by itself (3x3 = 9) then multiply by Pi (9x3.1416 = 28.2744). Now multiply by the length (28.2744x8 = 226.1952). The volume of the cylinder is 226.2 (rounded off) cubic inches.
The cylinder is one of the most basic curvilinear geometric shapes, the surface formed by the points at a fixed distance from a given line segment, the axis of the cylinder. The solid enclosed by this surface and by two planes perpendicular to the axis is also called a cylinder. The surface area and the volume of a cylinder have been known since antiquity.
In differential geometry, a cylinder is defined more broadly as any ruled surface spanned by a one-parameter family of parallel lines. A cylinder whose cross section is an ellipse, parabola or hyperbola is called an elliptic cylinder, parabolic cylinder or hyperbolic cylinder respectively.
