Step  4   Print the sum.

                 Step  5   Stop.


                 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.)
                                                                                2
                 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.
