Java Program to calculate Surface Area and Volume of Sphere

Welcome to the new tutorial Java Program to calculate Surface Area and Volume of Sphere of the Java Geometrical Calculation Programs series. In this post, we will learn to calculate the surface area and volume of the sphere in Java.

The previous tutorial of this series is Java Program to calculate volume of cone. Now here we will write a program to find the area and volume of the sphere in Java.

We can calculate the surface area and volume of the sphere using the following mathematical formula.formula.

Surface area of sphere, A = 4 π r²

Where,

π is a constant whose value is 3.1415 or 22/7
r is the radius of the sphere.

Volume of sphere, V = (4 ⁄ 3) π r³

Where,

π is a constant whose value is 3.1415 or 22/7
r is the radius of the sphere.

Now let’s write the program.

Java Program to calculate Surface Area and Volume of Sphere

import java.util.*; 
 
public class Sphere {
	public static void main(String[] args)
	
	{
		double r, area, volume;
		
		Scanner in = new Scanner(System.in);
                
                // Asking the user to enter the radius of the sphere
		System.out.println(" Enter the radius of the sphere :");
		r = in.nextDouble();

		area = 4 * Math.PI * r * r; // Calculating surface area of sphere
		volume = (4 * Math.PI * r * r)/3; // Calculating volume of sphere
 
		System.out.println(" Surface area of sphere  : " + area +" square units");
		System.out.println(" Volume of sphere : " + volume +" cubic units");
 
	}
	
}

import java.util.*;

public class Sphere {

public static void main(String[] args)

{

double r, area, volume;

Scanner in = new Scanner(System.in);

// Asking the user to enter the radius of the sphere

System.out.println(" Enter the radius of the sphere :");

r = in.nextDouble();

area = 4 * Math.PI * r * r; // Calculating surface area of sphere

volume = (4 * Math.PI * r * r)/3; // Calculating volume of sphere

System.out.println(" Surface area of sphere : " + area +" square units");

System.out.println(" Volume of sphere : " + volume +" cubic units");

}

What we did ?

First of all we have imported the util package.
Then created a class and named it Sphere.

After that started main() method of the program.
Then inside main() method declared variables.
Then created object of the Scanner class.

Now asked the user to enter the radius of the sphere. Then read the value of radius of the sphere entered by the user.
Then calculated surface area of the sphere using the formula area = 4 * Math.PI * r * r.
After that calculated volume of the sphere using the formula volume = (4 * Math.PI * r * r)/3.

Then finally displayed the value of the surface area and the volume of the sphere on the screen.

Output:

Enter the radius of the sphere :2
Surface area of sphere  : 50.26548245743669 square units
Volume of sphere : 16.755160819145562 cubic units

Enter the radius of the sphere :2

Surface area of sphere : 50.26548245743669 square units

Volume of sphere : 16.755160819145562 cubic units

The Java program to calculate surface area and volume of sphere has been successfully completed. In the next tutorial, we will learn Java Program to calculate Total Surface Area and Curved Surface Area of cylinder.
