Problem A $-$ Reflection Pond Measurements

Filename: pond.c

Welcome to UCF! In front of the library we have a beautiful reflection pond. $,$It has a foundation and during Spirit Week students get to jump in and have a pep rally. It is a lot of fun!

You have been tasked to find out the area that the pond covers. You will be given the radius of the pond. In this example you can assume that the pond is a perfect half circle.

You may need this formula:

$A=r^2$

Input Specification

Note: It is guaranteed that whoever uses your program will adhere to these specifications. This means that you do NOT have to check for them!

The radius entered will be integers in between $1$ and $100,$ inclusive.

Output Specification

Produce two lines of output with the following format:

area $=A$

where $A$ is the desired area. Please use $3\mathrm{.}14$ as pi to match the sample output.

Output Sample

Below is one sample output of running the program. Note that this sample is NOT a comprehensive test. You should test your program with different data than is shown here based on the specifications given above. In the sample run below, for clarity and ease of reading, the user input is given in italics while the program output is in bold. $($Note: When you actually run your program no bold or italics should appear at all. These are simply used in this description for clarity's sake.$)$

Sample Run #$1$

Enter the radius of the pond.

$9$

area $=127\mathrm{.}17$

Restrictions

Every program should include a header comment with the following information:

your name

Section Number

assignment title

date

Also, make sure you include comments throughout your code describing the major steps in solving the problem.
