Instructions

Create a new project in jdoodle called DataAndOperators$2$ and upload the three supporting files into it$.$ Once you have completed the lab, download the project, rename the $.$zip file as W$3\_$DataAndOperators$\_2$ and upload in Canvas.

Part A

You will need the code from PartA.java to complete this part of the lab. Make PartA as the Start File to run it$.$

Answer the following questions before compiling and running the code:

What should the output be if $2$ is entered as the radius $($use the calculator to determine this$)?$

Can you identify the need for the following statement:

import java.lang.Math.;;

Execute the code.

Was the output what you expected? Is the output correct?

This program is producing incorrect output because of a problem associated with types. Can you identify and fix the problem so that the output is correct?

After fixing the code, compile and execute it so you know it is running correctly.

Part B

You will need the code from PartB.java to complete this part of the lab. Make PartB as the Start File to run it$.$

Without running the code, can you determine what the output will be if you enter $2$ for b$1$ and $3$ for b$2?$ What if you enter $100$ for b$1$ and $2$ for b$2($more super bonus points if you answer this correctly$)?$

Execute the code to see if your answers were correct. If not, can you identify why not?

Can you fix the code so that it produces the value $200$ when you enter $100$ and $2?$
