CALCULATING THE AREA OF A CIRCLE
Step 1 Start.
Step 2 Read the radius of the circle and store it in r. (where, r is the length from the centre of
the circle to the edge of the circle.)

Step 3 Calculate the area of the circle. (Where, Area = π × r (3.14 × radius × radius))
Step 4 Print the area.
Step 5 Stop.
FLOWCHART
A flowchart is the graphical representation of a process and the logic (also referred to as an
algorithm) used in it. Flowcharts are used in analysing, designing, documenting or managing a
process or program in various fields.
SYMBOLS USED IN FLOWCHARTS
A flowchart uses specific geometrical shapes and directional arrows to draw a flow chart for a
particular task. A set of geometrical shapes represents the steps involved in the solution process.
Each shape represents a specific function, activity, or process. Directional arrows are used to
connect the shapes, indicating the flow of the solution.
Tick ( ) if you know this.
