title: Bounding Box Algorithm in Java with only the center points and the radius
body: <p>I am trying to create a circle in Java using the fillOval command. The user inputs the center co-ordinates and the radius for the circle but I do not know how to find the height and width for they fillOval command. </p>
  
  <pre><code>import java.util.*;
  import java.awt.*;
  
  public class Circles {
    public static final Scanner Console = new Scanner(System.in);
    public static void main(String args[]) {
  
  DrawingPanel panel = new DrawingPanel(400,300);
  Graphics g = panel.getGraphics();
  
  //print the beginning statement of the main method
  System.out.println("");
  
  //ask the user for the center and radius for the first circle
  System.out.println("Enter the x-value for the center of the first circle:    ");
  double x1 = Console.nextDouble();
  System.out.println("Enter the y-value for the center of the first circle: ");
  double y1 = Console.nextDouble();
  System.out.println("Enter the radius for the first circle: ");
  double rad1 = Console.nextDouble();
  
  //calculate the height and width of the first circle
  
  
  //ask the user for the center and radius for the second circle
  System.out.println("Enter the x-value for the center of the second circle: ");
  double x2 = Console.nextDouble();
  System.out.println("Enter the y-value for the center of the second circle: ");
  double y2 = Console.nextDouble();
  System.out.println("Enter the radius for the second circle: ");
  double rad2 = Console.nextDouble();
  
  //calculate the height and width of the second circle
  
  
  //ask the user for the center and radius for the third circle
  System.out.println("Enter the x-value for the center of the third circle: ");
  double x3 = Console.nextDouble();
  System.out.println("Enter the y-value for the center of the third circle: ");
  double y3 = Console.nextDouble();
  System.out.println("Enter the radius for the third circle: ");
  double rad3 = Console.nextDouble();
  
  //calculate the height and width of the third circle
  
  
  //use the fillOval method to draw each circle
  //fillOval(int x, int y, int width, int height)
  </code></pre>
  
  <p>This is all I have so far. Im just not sure how to obtain the height and width.</p>
