Overview

Let’s create a flowchart to calculate the area of the given radius of the circle using the Flowgorithm flowchart tool. At the end of this tutorial, you should be able to create a flow chart using the Flowgorithm application to compute the Area of a circle.

IPO chart

Input, Process, and Output chart.

Input	Process	Output
The radius of the circle(radius)	Area = pi * radius * radius	Area of the circle(Area)

Flowchart

The general steps to create the flowchart are as follows:

• Launch the Flowgorithm app.
• Save the flowchart with AreaCircle.fprg ( File >> Save menu option)
• Right-click and add a Declare variable called: radius
• In the variable Type, drop-down choose:  Real
• Repeat the same, right-click, and add a Declare variable called: Area

Prompt the User

Now, we will prompt the user to enter the circle’s radius. To add an Output symbol, right-click and add the output symbol. Click on the Output symbol and enter the user prompt.

“Enter the radius of the circle =”

Add an input symbol to store the value entered by the user. Click on the Input symbol and type radius.

Calculate the Area

Now, we need to compute the area of the circle. Add an Assign flowchart symbol and double-click on it.

Area = 3.14 * radius * radius

Now, we need to output the computation dome to the user. Add an Output symbol and double-click on it.

“The area of the Circle is = ” & Area

& is a string concatenation symbol in the Flowgorithm flowchart tool.

Run the flowchart

Run the flowchart to compute the area of the circle.

Enter the radius of the circle =
2.5
The area of the Circle is = 19.625

 

That’s it. We have successfully created a flowchart to compute the area of the given circle.
