Write a method that prints on the screen a message stating whether 2 circles touch each other, do not touch each other or inters

beks73 [17]

Answer:

The method is as follows:

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

if(d == r1 + r2){

System.out.print("The circles touch each other"); }

else if(d > r1 + r2){

System.out.print("The circles do not touch each other"); }

else{

System.out.print("The circles intersect"); }

}

Explanation:

This defines the method

public static void checkIntersection(double x1, double y1, double r1, double x2, double y2, double r2){

This calculate the distance

double d = Math.sqrt(Math.pow((x1 - x2),2) + Math.pow((y1 - y2),2));

If the distance equals the sum of both radii, then the circles touch one another

if(d == r1 + r2){

System.out.print("The circles touch each other"); }

If the distance is greater than the sum of both radii, then the circles do not touch one another

else if(d > r1 + r2){

System.out.print("The circles do not touch each other"); }

If the distance is less than the sum of both radii, then the circles intersect

else{

System.out.print("The circles intersect"); }

}
