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 *Π * 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.
