Circle
This example demonstrates the calculation of the area and perimeter of a semicircle. Key mathematical concepts include the properties of a circle, area, and perimeter formulas. Using GeoGebra commands such as Intersect, Semicircle, Area, and Circumference, the geometric construction of a semicircle is visually illustrated. Suitable for students at the middle school level and above to learn geometric construction and properties of circles.

GeoGebra Commands & Parameters

  1. Intersect(xAxis, yAxis) → A
  2. Segment(A, B) → g
  3. Semicircle(A, B) → c
  4. Semicircle(A, B) → d
  5. Area(Semicircle[A, B]) → a
  6. Circumference(Semicircle[A, B]) → b
  7. Midpoint(A, B) → C
  8. Segment(A, C) → h
  9. Distance(A, C) → AC
