This example demonstrates how to calculate the surface area and volume of a cylinder using GeoGebra. Key mathematical concepts include the geometric properties of a cylinder, as well as the formulas for surface area and volume. Using commands like Random, Intersect, Circle, and Cylinder, users can dynamically adjust the cylinder's dimensions and observe changes in surface area and volume. Suitable for middle school and above students and teachers.

GeoGebra Commands & Parameters

  1. Random(1, 5) → n
  2. Random(1, 9) → i
  3. Intersect(xAxis, yAxis) → A
  4. Circle(A, n) → c
  5. Cylinder(c, i) → a, d, b
  6. Intersect(xAxis, yAxis) → B
  7. Point(c) → C_1
  8. Segment(B, C_1) → r
  9. Point(d) → D
  10. OrthogonalLine(D, xOyPlane) → j
  11. Intersect(j, c, 1) → E
  12. Segment(D, E) → h
  13. Intersect(c, yAxis, 2) → F
  14. Polygon(F, I, H, G) → poly1, C, i_1, h_1, g_1
  15. Circle(J, n) → p
