    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.
