Question

using Java

The formula to compute the volume of a sphere is:

volume = ( 4 3 ) π r 3

where r is the radius of the sphere and π is 3.14159.

Assume a variable radius has already been declared (type double) and initialized with the value of the radius of a sphere.

Write java statements to do the following:

• Declare a constant PI and initialize it to 3.14159
• Declare a variable volume of type double
• Calculate the volume of the sphere and store it in the variable volume.
• Display the computed volume on the console.

Answer 1

import java.util.Scanner;

public class VolumeOfSphere {

public static void main(String args[]) {

final double PI = 3.14159; // declaring and initializing a CONSTANT using FINAL keyword

double volume; // declaring variable VOLUME of type double

double radius = 3.5; // declaring and initializing radius

volume = (4.0 / 3.0) * PI * (radius * radius * radius); // volume of sphere = 4/3 * PI * r^3

System.out.println("Volume Of Sphere is:" + volume); // Displaying the volume of sphere in the console

}

}
