Calling Methods Again [so, are you guys sick of me yet?]

So! I finally think I understand writing a method! ...of course...I
still can't seem to figure out how to call it right, and therefore I
don't know if the method is right *if that made any sense*.

This is what I have so far *hides*:

/**
 * @(#)try1.java
 *
 * try1 application
 *
 * @author
 * @version 1.00 2008/4/1
 */
 import java.util.*;
 import javax.swing.*;
 import java.io.*;
public class try1 {

    public static void main(String[] args)throws FileNotFoundException
{
     Scanner fileIn = new Scanner(new FileReader("Cylinders.txt"));
     PrintWriter fileOut = new PrintWriter("Output3.txt");
        System.fileOut.print("Please Enter The Radius: ");
        float radius = fileIn.nextFloat();
        System.fileOut.print("Please Enter The Height: ");
        float height = fileIn.nextFloat();
        System.fileOut.println("Height= " + height + ", Radius= " + radius +
", Base Area= " + area + ", Lateral Area= " + latArea + ", Surface
Area= " + surfArea + ", Volume= " + volume);

    }

    public static float baseArea(float radius){
     float area;
     area = 3.14*radius*radius;
     return area;
    }

    public static float latArea(float radius, float height){
     float circum = (radius*2)*3.14;
     latArea = circum * height;
     return latArea;
    }

    public static float surfArea(float area, float latArea){
     float surfArea = (area*2)+latArea;
     return surfArea;
    }

    public static float volume(float area, float height){
     float volume = area*height;
     return volume;
    }

    fileIn.close();
    fileOut.close();
}
