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).

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.

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.You will need

- calculator

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 cylinder**than its diameter or radius. To calculate the volume**of a cylinder**if 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

- the volume

**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.
