圆台体积计算公式 - 百度知道
圆锥体积的计算公式是:V=1/3Sh(V=1/3πr^2h)S是底面积,h是高,r是底面半径。 圆台是圆锥被截去上面小圆锥部分所形成。 故而其体积的计算公式实为两圆锥体积计算公式的相减。 所以其计算公式为:V (圆台)=V (大圆锥)-V (被截小圆锥),及:V (圆台)=1/3π(R^2H-r^2h),其中R为圆台底面圆半径,r为圆台顶面圆半径,H为大圆锥高,h为被截小圆锥高,而圆台高度则为:H-h。 圆台体积计算公式V=1/3πh(r²+R²+rR)解释:圆台的上、下底面的半径分别是r,R,高 …
圆台体积公式详解 - 百家号
2023年5月17日 · 圆柱的体积公式为V2 = πR^2h2。 现在,我们需要计算圆锥和圆柱的交界面积,以便计算圆台的体积。 圆锥和圆柱的交界面积是一个圆台形状的截面,其底面半径为R,顶面半径为r,高为h1。 因此,它的面积可以用以下公式表示:A = (1/2)π (R + r)l,其中l是圆台的母线长度,可用勾股定理求得:l^2 = (R - r)^2 + h1^2。 现在,我们可以计算圆台的体积了。 根据圆台的定义,圆台的体积等于圆锥和圆柱的体积之和。 因此,我们有V = V1 + V2 = (1/3)πr^2h1 + …

What is the Formula for the Volume of a Sphere? - Virtual Nerd
Summary. The radius of the sphere is the same as the radius of the cylinder's bases: 7 centimeters; A circle through the middle of the sphere is the same size as the cylinder's bases
Why is the volume of a sphere $\\frac{4}{3}\\pi r^3$?
To find the volume of a sphere of radius then, just add up the areas of infinitesimally thin disks on as goes from to . To work it out: This is exactly how I first found the volume of the sphere (and likely thousands of people before me), it's the most straightforward way. I think this is the most appropriate answer to the question.
