Purpose
    · Calculate areas of composite shapes
· Calculate the surface area and volume of cylinders and solve related problems
· Solve problems involving the surface area and volume of right prisms
    Conditions
    Students typically work on guided problem-solving and modelling tasks. The teacher influences the concepts and techniques chosen, and/or the model students use to solve the problem. The teacher provides guidance and all stages of the problem-solving and modelling approach are used.
    Instructions
    A problem-solving and modelling task requires students to:
· analyse information and data
· process information
· interpret and synthesise data
· explain relationships to develop and support mathematical arguments
· reflect on and evaluate data, propositions, results and conclusions
· communicate ideas.
    To complete this task, you must:
    ⃝ Use your knowledge of measurement outlined in Topic 12 of Jacaranda Maths Quest 9
    ⃝ Show all calculations to support your response.
    ⃝ Show all units in your answers.
    ⃝ Write the task in basic report form including Introduction, Body and Conclusion
    Checkpoints
