This math topic focuses on calculating the area of a circle from its radius. Multiple problems are provided for practice, requiring the learner to apply the formula A = πr², where "A" is the area and "r" is the radius of the circle. Answers to the problems are given as well, enabling self-correction. This topic is part of a broader unit on introductory circle area geometry.
