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))

FLOWCHART
A flowchart is the graphical representation of a process and the logic (which is also called an
algorithm) used in it. Flowcharts are used in a variety of fields to analyze, design, document, or
manage a process or program.
SYMBOLS USED IN FLOWCHART
A flowchart uses specific geometrical shapes and directional arrows to represent a particular
task. A set of geometrical boxes represents the steps involved in the solution process. Each box
represents a specific function, activity, or process. Directional arrows are used to connect the
boxes to show the flow of the solution.
