This podcast is made by Ran Chen, who holds an EA license, Insurance and Securities licenses (Series 6, 63, 65), and the CFP® designation. He is passionate about opening access to high-quality exam preparation resources and helping learners prepare more effectively for professional certification exams. In this episode you will learn: - To distinguish and apply the circumference (2πr) and area (πr²) formulas, especially when given the diameter. - How to calculate arc length and sector area as fractional parts of a circle's circumference and area. - The inscribed angle theorem, stating that an inscribed angle is half the central angle intercepting the same arc. - The critical property that a tangent line is always perpendicular to the radius at the point of tangency. - How to avoid common AFOQT traps, such as confusing the radius with the diameter or mixing up fundamental formulas.
