This example demonstrates how to dynamically calculate the area of a circle. It involves core mathematical concepts such as the area formula of a circle, geometric construction, and coordinate geometry. Key GeoGebra commands used include Circle, Segment, Area, PointIn, Point, Text, and Slider. Suitable for middle school students and above to learn and understand the calculation method and dynamic geometric properties of the circle's area.

GeoGebra Commands & Parameters

  1. Circle(A, B) → c
  2. Segment(A, B) → f
  3. Area(c) → a
  4. PointIn(c) → Pointc
