To create a flowchart for the provided pseudo code, you can follow these steps visually organized in a standard flowchart format. Below is a textual representation of how you would lay out the flowchart:
Flowchart Steps
-
Start: Begin the flowchart with a "Start" symbol (oval shape).
-
Input Radius: Use a parallelogram to represent the action of entering the radius.
-
Decision (If): Create a diamond shape for the decision point:
- Condition:
radius < 0
a. Yes (True):
- Connect to a process box saying "Display error message."
- Connect to a process box saying "Re-enter positive radius."
- Then, loop back to the "Input Radius".
b. No (False):
- Move on to the next process box saying "Enter height."
- Condition:
-
Input Height: Use another parallelogram for entering the height.
-
Calculate Volume: Use a process box to represent calculating the volume:
- Volume = (1/2) × π × (radius²) × height
-
Display Volume: Use a parallelogram for displaying the volume.
-
Stop: End the flowchart with an "End" symbol (oval shape).

How to Draw
- Begin with an oval shape for "Start" and label it.
- Use a parallelogram to indicate "Enter Radius".
- Create a decision shape (diamond) for the condition
radius < 0. - Branch out for "Yes" (display error and re-enter radius) and "No" (enter height).
- For the "Yes" path, include another parallelogram to indicate re-entering the radius, and link it back to the "Enter Radius" step.
- For the "No" path, include another parallelogram to enter the height.
- From there, have a process box for calculating the volume.
- Finally, use a parallelogram to display the volume and then end with an oval shape for "Stop".
