Advice 1: How to know the engine size

So, after much deliberation and comparisons of one brand relative to another, you still stopped for a single model automobile. Finally the day came - the car is yours. After purchase, vehicles are often in the mind of the motorist maturing issue, the question of what is actually the volume of the engine and is not deceived if the dealer in the showroom.

Instruction
1
To learn such important characteristic, as the volume engine, it is enough to look in the data sheet.
2
Also the volume can be determined by VIN-code (individual identification number of the vehicle), which can be seen from the bottom of the arch of the driver's door (of course, if the door is open), under the rear seat or directly under the windshield, in the upper left part of the dashboard (in this case, the desired code can only be seen from outside the vehicle).
3
Some "craftsmen" advise you to Unscrew the plugs and pour water to the eyeballs: how much water fit, this is the volume. It is not necessary to take seriously this advice. Actually it's just an old joke.
4
If you have a used car, the data from the data sheets may not be true. Who knows, maybe the car was involved in an accident, can the car hold any of the technical work affecting the characteristics of the engine. Maybe it is generally assembled from several vehicles. The volume of the engine in such cases you can define in the following way: on the back of the engine block in large letters can be cast in volume (to watch the pit bottom rear).
5
But still, the surest way to determine the amount the engine is to check via the VIN code, which was written above. After reading a number of useful tips at you will not arise questions about the important characteristics of the vehicle, as the volume of the engine.

Advice 2: How to find the volume of a cylinder

In solving mathematical and technical problems sometimes it is necessary to know the volume of the cylinder. A similar problem often arises in the everyday life, as many containers (drums, pails, cans, etc.) have a cylindrical shape. Of course, if you know the radius and height (length) of the cylinder, its volume is very easy to calculate. However, in practice these options are not always specified, and the cylinders are not only direct circular.

1
To find the volume of a cylinder, multiply its height by the number "PI" and the square of the radius. As a formula this rule as follows: = V * π * R2, where the volume of the cylinder, height of cylinder, R is the base radius of the cylinder, π is the number PI, approximately equal to 3.14.The volume of the cylinder to be measured corresponding to the radius and height of the cubic units of measurement. Ie if, for example, the radius and height of cylinder are given in meters, the volume will in cubic meters (m3).The above rule applies only for "normal", i.e. straight circular cylinder (cylinder, whose base is a circle, and the guide perpendicular to it).
2
Example: height of cylinder is 5 cm and the base radius is 2 cm In this case its volume will be equal: 5 * π * 22 ≈ 62,831 cm3.The number π has many calculators and denoted usually by the Greek letter "PI" (π). On the virtual keyboard the standard Windows calculator (in engineering), the number is denoted as pi.
3
If instead the radius of the cylinder is set the diameter, use the following formula: = V * π * (D/2)2 or = ¼ * H * π * D2, where D is the diameter of the base of the cylinder.
4
Example: height and base diameter of the cylinder is 10 cm In this case) to know the volume, calculate the value of the following expression: 10 * π * (10/2)2 ≈ 785,398 cm3.
5
In practice, it is generally much easier to measure the perimeter (circumference) of the base of the cylinderthan its diameter or radius. To calculate the volume of a cylinderif you know the perimeter of his base, use the following formula:About = ¼ * B * N2 / p, where P is the perimeter of the base.When you use this formula to calculate the capacity of containers (dishes) please note that the actual capacity would be slightly less than calculated based on the volume of vessel walls).
6
According to the definition, the base of the cylinder can be an arbitrary line in the plane, and its image is not necessarily perpendicular to the base. In the General case to know the volume of the cylinder by the following rules:- the volume of a cylinder equals the length of the forming to the cross-sectional area of the cylinder by the plane perpendicular to the generatrix;
- the volume of a cylinder equals the area of the base to the height (distance between bases).
Note
The height of the cylinder - the concept is purely geometric. It means the distance between its bases and does not depend on the location of the cylinder in space.
