Prepare a data flow diagram for computing the volume and surface area of a cylinder. Inputs are the height and radius of the cylinder. Outputs are the volume and surface area of the cylinder. Discuss several ways of implementing the data flow diagram.
The data flow diagram for computing the volume and surface area of a cylinder is given in Figure below.
Figure: Data flow diagram for computing volume and surface area of a cylinder.
In this figure, object cylinder is represented by the rectangle. The processes compute volume and surface are by an ellipse, and data flow by the help of arrow. The formula for surface area and volume of represented cylinder can be taken respectively.
