This math topic covers the area of a circle, a subtopic in Geometry. It involves calculating the area of circles of different sizes without the use of a calculator. The learner is reminded that Pi is slightly more than 3. Some basic understanding of geometry, particularly cylinders, is also integrated. The task includes six questions, each requiring the computation of the areas of circles from different problems. Solutions are provided for each question.
