How do you calculate a cube of a log with a diameter of 40 centimeters and a length of 2 or 4 meters

The area formula for a cylinder.

is the base area multiplied by the height, the base is a circle, and the area of the circle is equal to the square of the pie multiplied by the radius. Because the diameter is 40 centimeters, which is meters, then the radius is meters, pi.

take, then the volume of the log is, is equal to cubic meters.

The diameter is 40 cm, the radius is meters, and the volume of the cylinder formula is equal to r square multiplied by the height, and the volume is cubic meters

Diameter 40 cm = 40 cm, radius = 20 cent.

Meter volume = square of work (multiplied by the square.

Diameter 40 cm, radius is.

meters, which is equal to the volume by the cylinder formula.

Multiply the IR square by the height to get: volume is.

Cubic metre.

Diameter 40 cm = 40 cm, radius = 20 cm Volume = ( multiplied by the square.

1 cm = 10mm, 40 cm = 400mm =, according to the volume formula.

v=πr²h

Glad to be able to answer your questions. To find the volume of the log, then it is necessary to use the formula of finding the volume of the cylinder to calculate, then the volume is v=s*h. Then find v = square meter.

Therefore, if you want to find the volume of the log, you must calculate the log as a cylinder, so it is more thoughtful. Hope mine can help you!

Summary. Pro, the calculation process is as follows: 1 meter = 100 centimeters 30 centimeters = meters cubic meters The diameter of the cubic meter is thirty centimeters, the length is square.

Dear, this question will take about two minutes, and I'll send it to you right away!

Thirty centimeters in diameter, how many square meters is the length?

Pro, the calculation of the Qing attack is as follows: 1 meter Yu Mo brother = 100 centimeters 30 centimeters = cubic meters of cubic meters of 30 centimeters in diameter, the length of the swim, is the square.

Dear, this question mainly concerns the volume formula of a cylinder. v= r hv is the volume of the cubic meter, is the pi to sell, r is the radius of the friend in meters, h is the height of the meter.

How many squares is ten barrels?

1 barrel of cubic meters, 10 barrels = cubic meters.

The log is 13 meters long and has a diameter of 40 centimeters.

Kiss! Hello, happy to answer your <>

The pro-log is 13 meters long and has a diameter of 40 centimeters, and the cubic log is a wooden segment that is cut into a certain length in the long direction according to the standard or special regulations of size, shape and quality, and this wooden segment is called a log. The log segment formed by the original strip is made of wood.

There are those with skin and those with skin. According to the material and use value of logs, it is divided into two categories: economic timber and charcoal timber. According to its use, economic timber is divided into direct use logs and processing logs.

The direct use of logs is divided into mining pit wood, house building purlins, etc. Logs for processing can also be divided into premium logs, conifer processing logs and hardwood processing logs. These logs, as the main products of the forest industry, must meet the national timber standards.

Hope mine can help you <>

Do you have any other questions?

How many 4x6 squares can be produced from a log with a diameter of 20 cm and a length of 4 meters?

How many 4*6 wood squares with a diameter of 20 cm and a length of 4 meters can be dismantled? How many roots are on the side of the wooden square of 4 cm by 6 cm. First of all, we have to calculate how many meters there are in the wood square of 4 times 6, divide by 1 and divide by equal to rice sweet, first calculate with 3 meters long each root is equal to about 139, if it is calculated with 4 meters per root, it is about equal to 104 sticks.

The 4x6 wood cube can be used to search the joint of the woodworking board under the cast-in-place board, or we can use the main keel for decoration.

The diameter of 20 centimeters is meters, the radius is meters, and the volume is cubic meters.

Effects of wood:

China's per capita timber occupancy is small, and China's timber throughput as a developing country is huge, because of the loss of silver limbs every year has to rely on a large number of imports, according to the survey, China's timber throughput ranks first in the world.

China is the world's largest timber demand, since 2003 has been growing at a rate of 10 percent per year, although China has a large land, but the production of timber in the hungry country still can not meet domestic demand, every year has to import a large number of timber from the world to meet domestic development needs, which macro-control of the global timber. <>

Summary. There are tons of 15 red sour branches with a diameter of 40 centimeters and a length of wood.

How many squares are 15 pieces of wood with a diameter of 40 centimeters and a length of 15 meters.

Please wait a moment.

There are tons of 15 red sour branches with a diameter of 40 centimeters and a length of wood.

1. If the timber refers to the log, and the diameter refers to the diameter of the small head, the volume is cubic meters;

2. If the timber refers to the log, and the diameter refers to the diameter of the large head, according to the calculation of 1% of the normal trunk tip cut, and the small head is 28 cm, the volume is cubic meters;

3. If the timber referred to refers to the cylindrical cavity and the diameter refers to the diameter of any of its places, then: r r length = and volume is cubic meters.
