The method on line 92 is not initiating the formula for option 3. Why is this?

Well, I was testing your program and I noticed that your menu(); repeats itself before actually using your switch. For example,

Code java:

---

What is the name of the program? 5
What is the due date of the program? 5
The program name is: 5
The due date of the program is: 5
* * * * * * * * M E N U * * * * * * * *
 
1>   Area of a circle
2>    Circumference of a circle
3>    Area of a rectangle
4>   Perimeter of a rectangle
5>    Volume of a box
6>    Volume of a cone
Enter your choice: 3
* * * * * * * * M E N U * * * * * * * *
 
1>   Area of a circle
2>    Circumference of a circle
3>    Area of a rectangle
4>   Perimeter of a rectangle
5>    Volume of a box
6>    Volume of a cone
Enter your choice: 3
Enter the length: 4
Enter the width: 5
The area of the rectangle is 20

So i just took out the menu(); that was by itself since the first one didn't do anything. Also, I think the reason why your method wasn't initiating was because

Code java:

---

case 3:
                System.out.print("Enter the length: ");
		length=kb1.nextInt();
		System.out.print("Enter the width: ");
		width=kb1.nextInt();                         // this was length, instead of width
		int iAreaRectangle;
		iAreaRectangle = areaRectangle(length, width);
		System.out.print("The area of the rectangle is " +iAreaRectangle);

Thank you, I figured it out before you posted thankfully, but you guys are very helpful, and I appreciate it very much.
