Intro to Java

Hey so I'm taking a intro to java class and I'm told to (Computing the volume of a cylinder) Write a program that reads in the radius and length of a cylinder and computes volume using the following formulas:
area = r*r*pi
volume= area*length

In the end the program is suppose to say "The area is...The volume is..."
This is what I have so far but I am totally lost. Also let me know if it should use another way to show my code vs copy and paste. Please let me know what I am doing wrong.


import java.util.Scanner;


public class VolumeOfACylinder {

public static void main(String[] args){

// area = radius * radius * 3.14159

Scanner scum = new Scanner(System.in);

double radius = scum.nextDouble();

System.out.println("Please enter the radius: ");

double area;

area = radius * radius * 3.14159;

// volume = area * length

Scanner solo = new Scanner(System.in);

double area;

double lenth = solo.nextDouble();

System.out.println("Please enter the length: ");

double volume;

volume = area * length;

System.out.println("The area is " + area + "and the volume is " + area * length );
}
}

That way is good. One more thing to be done is wrap the code in code tags:

[code=java]

<YOUR CODE HERE>

[/code]

to get highlighting and preserve formatting.

Okay still I still need help with the code idk why its not running.

Code java:

---

import java.util.Scanner;
 
 
public class VolumeOfACylinder {
 
public static void main(String[] args){
 
// area = radius * radius * 3.14159 
 
Scanner scum = new Scanner(System.in);
 
double radius = scum.nextDouble();
 
System.out.println("Please enter the radius: ");
 
double area;
 
area = radius * radius * 3.14159;
 
//	volume = area * length
 
Scanner solo = new Scanner(System.in);
 
double area; 
 
double lenth = solo.nextDouble();
 
System.out.println("Please enter the length: ");
 
double volume;
 
volume = area * length; 
 
System.out.println("The area is " + area + "and the volume is " + area * length );
}
}

The formatting still needs work. The statements are not properly indented. Not all statements should start in the first column.

Please copy the full text of the error messages and paste it here.
Otherwise explain what "not running" means.
