# Calculate Area of the Circle Flowgorithm Flowchart

# Overview

Let’s create a flow chart 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 radius of the circle. 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 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.
