In this post, we will see how to calculate total surface area of Hemisphere in java.
Hemisphere is exactly half of sphere.
There can be many practical examples of Hemisphere. You can divide earth into two hemisphere i.e. Northen Hemisphere and Southern Hemisphere.
Formula of calculating total surface area of Hemisphere is:
surface area of Hemisphere = 2 *Î * r * r
Where r is radius of hemisphere.
Where r is radius of hemisphere.
Here is java program to calculate total surface area of Hemisphere. We are using scanner class to take input from user in below program.

package org.arpit.java2blog; import java.util.Scanner; public class TotalSurfaceAreaHemisphereMain { public static void main(String[] args) { Scanner s= new Scanner(System.in); System.out.println("Enter the radius of hemisphere :"); double r=s.nextDouble(); double surfaceAreaHemisphere= 2 * Math.PI * r * r; System.out.println("Total surface area of Hemisphere is: "+surfaceAreaHemisphere); s.close(); } } |
When you run above program, you will get below output
Enter the radius of hemisphere :
3
Total surface area of Hemisphere is: 56.548667764616276
3
Total surface area of Hemisphere is: 56.548667764616276
That’s all about how to calculate total surface area Hemisphere in java.
