MHB Calculate Sphere Volume Using (4.0/3.0) Division

AI Thread Summary
To compute the volume of a sphere using the formula V = (4/3)πr³, the code requires the correct implementation of floating-point division. The value of pi is set to 3.14159, and the sphere's radius is initialized to 1.0. The calculation for sphereVolume should be performed using the expression (4.0 / 3.0) * piVal * Math.pow(sphereRadius, 3). This ensures that the result is accurate and utilizes the floating-point division necessary for precise calculations. The final output should display the computed sphere volume.

Given sphereRadius and piVal, compute the volume of a sphere and assign to sphereVolume. Use (4.0 / 3.0) to perform floating-point division, instead of (4 / 3) which performs integer division.

Code:
public class SphereVolumeCalculator {
   public static void main (String [] args) {
      double piVal = 3.14159;
      double sphereVolume = 0.0;
      double sphereRadius = 0.0;

      sphereRadius = 1.0;

     

      System.out.println("Sphere volume: " + sphereVolume);
      return;
   }
}

The volume $V$ of a sphere having radius $r$ is given by:

$$V=\frac{4}{3}\pi r^3$$

So, can you use that to construct the needed statement?
 
Thread 'Star maps using Blender'
Blender just recently dropped a new version, 4.5(with 5.0 on the horizon), and within it was a new feature for which I immediately thought of a use for. The new feature was a .csv importer for Geometry nodes. Geometry nodes are a method of modelling that uses a node tree to create 3D models which offers more flexibility than straight modeling does. The .csv importer node allows you to bring in a .csv file and use the data in it to control aspects of your model. So for example, if you...
I tried a web search "the loss of programming ", and found an article saying that all aspects of writing, developing, and testing software programs will one day all be handled through artificial intelligence. One must wonder then, who is responsible. WHO is responsible for any problems, bugs, deficiencies, or whatever malfunctions which the programs make their users endure? Things may work wrong however the "wrong" happens. AI needs to fix the problems for the users. Any way to...
