# Calculate the Area of the Circle using Flowgorithm

### Overview

Let’s create a flow chart to calculate the area 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.

Basic flowchart operations are listed here:

### IPO chart

Input |
Process |
Output |

Radius of the circle(radius) | Area = pi * radius * radius | Area of the circle(Area) |

### Flowgorithm flowchart

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
