This topic is focused on the calculation of the area of a circle using the diameter. It's a fundamental aspect of Geometry, specifically focusing on the introductory knowledge of the area of a circle. The practice involves performing non-calculator computations, reinforcing the need to understand and apply the appropriate mathematical formula offline. It presents five different questions, each followed by multiple potential answers for students to choose from.
