Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.
Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these.
Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.
Good day Mathletes! This module was designed and written to help you gain an understanding of and to test your ability in solving routine and non-routine word problems involving the area of a circle. We know that the formula serves as a guide in solving for the area of a circle. Knowing how to derive the formula of the area of a circle and how to use it in real-life situations is important.
So, what are you waiting for? Stay focused and start-up.
At the end of this module, you are expected to:
- describe the different terms used in the formula;
- appreciate the importance of the formula in finding the area of a circle; and
- solve routine and non-routine problems involving the area of a circle.
Before going any further, let us check your understanding of the formula in finding the area of a circle.
