圆椎体积公式A

圆椎体积公式A 圆椎的体积与单元检测 (1) 圆锥的特征: 圆锥有一个底面和一个侧面，它的底面是个圆，侧面是一个曲面(从圆锥的顶点到底面圆心的距离叫圆锥的高，它只有一条高( (2) 圆锥的体积计算公式: 圆锥的体积等于和它等底等高的圆柱体积的三分之一(用字母表示 在解题时不要忘掉”，还要注意只有在“等底等高”的情况下，圆锥的体积才等于圆柱的体积的。 计算圆锥形容器的容积时，也用体积公式进行计算(但体和容积是不同的概念，体积是指物体所占空间的大小，而容积是指容器所能容纳物体的体积，虽然计算公式一样，但要注意它们的区别( 计算圆锥形容器的容积时，也用体积公式进行计算(但体和容积是不同的概念，体积是指物体所占空间的大小，而容积是指容器所能容纳物体的体积，虽然计算公式一样，但要注意它们的区别( 例1、 一个圆锥体的谷堆，底面周长9.42米，高1.8米，它的体积是多少立方米, ?求半径:9.42?3.14?2=1.5米 ?求体积: ×1.5×1.5×3×3.14×1.8=4.239(立方米) 答:这个谷堆的体积是4.239立方米( 例2、 一个圆锥形容器，从量面量高为15厘米，底面半径8厘米，容器装满水，这个容器可 装水多少毫升, ×3.14×8×8×15=100.48(立方厘米) =100. 48毫升 答:这个容器可装100.48毫升( 从以上两题可以看出，有两个不同点，一是单位名称不同，二是测量不同，计算体积时要从物体外部测量后计算，计算容积时，要从物体内部测量计算( 例3、 一个圆锥形容器，可容水122.46毫升，已知底面直径是6厘米，高是多少厘米, :这是一道逆向思维的题，用方程解比较容易，根据公式，对号入座，即可解决( 解:设高为x厘米 obstacles, correcting misunderstandings, advocate good cadre style. 2, adhere to the scientific decision-making and democratic decision-making decision-making law. Correctly handle to ensure that government decrees and based on the actual creative work, giving full play to subjective initiative, put an end to implement the conference meeting, to document the implementation of documents etc. Improve the scientific and democratic decision-making mechanism, improve and implement the decision to solicit the views of experts, the public hearing system. Improve the important decision of risk assessment mechanism and legal review mechanism. 3, to promote team unity.
