Complete the trace table using the program in Figure 3. - AQA - GCSE Computer Science - Question 3 - 2023 - Paper 1

To complete the trace table, you first need to understand what the program in Figure 3 does. It likely involves calculating volume based on certain parameters, which might be provided in the description of Figure 3.

1. Understand the program structure: Identify variables being used to compute the volume. Commonly, the volume of geometric shapes can be represented mathematically. For example:

   • For a cube: $V = a^3$
   • For a cylinder: $V = pi r^2 h$

2. Trace variable changes: As per the program flow, track how each variable changes through the execution of the program. Typically, this entails noting down how inputs modify your volume calculations.

3. Fill the trace table: Use the collected data from the previous steps to systematically populate the trace table. Each row should reflect a step in the execution highlighting values of key variables like inputs, computed volume, etc.

By following these steps and understanding how the program operates, you will be able to accurately complete the trace table.
