pom圆棒重量计算公式

英文回答：

The formula for calculating the weight of a pom

cylindrical rod is quite simple. We can use the formula:

weight = volume × density. To calculate the volume of the

rod, we need to know its length and diameter. The formula

for calculating the volume of a cylinder is: volume = π ×

(diameter/2)^2 × length. In this formula, π represents

the mathematical constant pi, which is approximately equal

to 3.14159. The diameter of the rod should be measured in

the same unit as the length.

Let's say we have a pom cylindrical rod with a length

of 10 centimeters and a diameter of 2 centimeters. First,

we need to calculate the volume using the formula mentioned

earlier. The diameter divided by 2 is equal to 1 centimeter,

and when squared, it becomes 1 square centimeter.

Multiplying this by the length of 10 centimeters and then

by π, we get a volume of approximately 31.4159 cubic

centimeters.

Now that we have the volume, we can calculate the

weight by multiplying it with the density of the pom

material. The density of pom can vary depending on its

grade and composition, but let's assume it is 1.4 grams per

cubic centimeter for this example. Multiplying the volume

of 31.4159 cubic centimeters by the density of 1.4 grams

per cubic centimeter, we get a weight of approximately

43.9823 grams.

计算pom圆棒重量的公式非常简单。我们可以使用公式，重量

= 体积 × 密度。要计算圆棒的体积，我们需要知道其长度和直径。

计算圆柱体积的公式是，体积 = π × (直径/2)^2 × 长度。在这

个公式中，π代表数学常数pi，约等于3.14159。圆棒的直径应该

使用与长度相同的单位进行测量。

假设我们有一根长度为10厘米，直径为2厘米的pom圆棒。首

先，我们需要使用前面提到的公式计算体积。直径除以2等于1厘

米，平方后变为1平方厘米。将这个值乘以长度10厘米，再乘以

π，我们得到约为31.4159立方厘米的体积。

现在我们有了体积，可以通过将其与pom材料的密度相乘来计

算重量。pom的密度可以根据其等级和组成而有所不同，但假设本

例中为1.4克/立方厘米。将31.4159立方厘米的体积乘以1.4克/

立方厘米的密度，我们得到约为43.9823克的重量。
