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:

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.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
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
