计算球体的体积和表面积
原文:https://www . geesforgeks . org/calculate-volume-surface-area-sphere/
给定球体半径，计算球体的体积和表面积。
球体:
就像一个圆，它在几何上是一个二维物体，球体在数学上被定义为一组点，这些点都离给定点有相同的距离 r ，但在三维空间中。这个距离 r 就是球体的半径，给定点就是球体的中心。
对于给定的表面积，球体是体积最大的固体。这就是为什么它在自然界中出现如此之多，如水滴、气泡和行星等。
球体体积:
精确填充球体的立方单位数或球体的存储容量。我们可以用公式
计算球体的体积
![Volume Of Sphere]()
球体表面积:
球体物体的表面积是球体表面所占总面积的量度。我们可以用公式
计算球体的体积
![Surface area Of Sphere]()
例:
Input : Radius Of Sphere = 5
Output : Volume Of Sphere : 523.5987755982989
Surface Area Of Sphere : 314.1592653589793
Explanation:
Volume =( 4/3 ) * 3.14159 * 5 * 5 * 5 = 523.598
Surface Area = 4 * 3.14159 * 5 * 5 =314.159
Input : Radius Of Sphere = 12
Output : Volume Of Sphere : 7238.229473870883
Surface Area Of Sphere : 1809.5573684677208
