Hi, in this tutorial you will learn how to design a flowchart to compute the area of
00:11
circle with radius r.
00:15
The mathematical formula for the area of circle is pi star r square.
00:23
So pi is a mathematical constant and r is the radius of the given circle.
00:32
So in the flowchart we will prompt the user to enter the radius of the circle that is
00:38
r.
00:40
Launch the flow graph application from the start menu.
00:43
Initially you will get two flowchart symbols main and end.
00:49
You can design the flowchart by adding the symbols within these two symbols.
00:55
So right click on the control line and declare a variable called area.
01:02
This denotes the area of the circle and let's declare another variable called radius.
01:11
We will specify it as r which is of type real and let's initialize the variables to 0 and
01:26
specify the radius r and in the right hand side specify 0.
01:33
Similarly give the variable area and specify 0.
01:40
Now we are initializing these two variables to 0.
01:46
Now let's prompt the user to enter the radius of the circle.
02:09
So this will prompt the user to enter the radius of the circle.
02:16
Take the user input into the variable r so let's specify r.
02:24
Now take an assign symbol and compute the area of the circle.
02:36
So to use pi we can specify these two letters which denotes the pi constant in flow algorithm.
02:48
So as a convention we will use the capital letter for a constant.
02:54
So now specify the variable r.
03:01
You can either specify it as again star r to calculus or you can use the exponential
03:08
operator carrot symbol and click on ok.
03:22
This will compute the radius, the area of the circle and store it in the variable called
03:28
area.
03:29
Now display the area of the circle.
03:50
This will display the area of the circle.
03:57
That's it we are done with the flowchart.
04:00
Let's test the flowchart by running the flowchart.
04:04
Click on the play button, enter the radius of the circle, enter 3.
04:12
Now you can see that the area of the circle got displayed in the control window.
04:22
That's it and this is the flowchart for calculating the area of the circle.
04:30
Thanks for watching.
