Java Program to Find the Volume and Surface Area of Sphere
A sphere is a geometrical object in 3D space that is the surface of a ball. The sphere is defined mathematically as the set of points that are all at the same distance of radius from a given point in a 3D space.
Example:
Input: radius = 5
Output: Surface Area ≈ 314.16
Volume ≈ 523.6
Input : radius = 3
Output: Surface Area ≈ 113.1
Volume ≈ 113.1
Surface area of a sphere = 4*3.14*(r*r)
Volume of a sphere = (4/3)*3.14*(r*r*r)
Algorithm
- Initializing value of r as 5.0, surface area as 0.0,volume as 0.0
- Calculating surface area and volume of a sphere using the below formulas
- Surface area=4*3.14(r*r)
- Volume=(4/3)3.14(r*r*r)
- Display surface area and volume
Implementation:
Java
// Java Program to Find the Volume and Surface Area of// Sphereclass surfaceareaandvolume { public static void main(String[] args) { double r = 5.0, surfacearea = 0.0, volume = 0.0; surfacearea = 4 * 3.14 * (r * r); volume = ((double)4 / 3) * 3.14 * (r * r * r); System.out.println("surfacearea of sphere =" + surfacearea); System.out.println("volume of sphere =" + volume); }} |
Output
surfacearea of sphere =314.0 volume of sphere =523.3333333333334
Time Complexity: O(1)
Space Complexity: O(1)
