Question

Write a program to find the radius of a circle which has the same area as the triangle with the sides (5cm, 7cm, 8 cm) have. Using JAVA

Answer 1

package My_Program;

public class Main {

   public static void main(String[] args) {

       // Calculating the area of the triangle

       double s1 = 5, s2 = 7, s3 = 8;

       double p = (s1+s2+s3)/2;

       double area = Math.sqrt(p*(p-s1)*(p-s2)*(p-s3));

       // Calculating the radius of the circle

       // from the area of the triangle, as they are same

       double radius = Math.sqrt(7 * area / 22);

       // Printing the radius of the circle

       System.out.println("Radius of the circle: " + radius);

   }

}
