This worksheet dynamically demonstrates the surface area of a cylinder, focusing on the properties of circles and solid geometry. Using GeoGebra commands such as Circle, Rotate, Segment, and Polygon, students can visually understand the composition of a cylinder's surface area. Suitable for middle school and above students studying geometry and solid geometry.

GeoGebra Commands & Parameters

  1. Circle(A, Radius) → c
  2. Point(c) → B
  3. Rotate(B, -α, A) → B'
  4. Segment(C, E) → a
  5. Segment(E, F) → d
  6. Segment(F, D) → e
  7. Segment(D, C) → f
  8. Polygon(C, D, F, E) → poly1, c_1, d_1, f_1, e_1
  9. Circle(G, Radius) → g
  10. Intersect(c, a, 1) → H
  11. Segment(A, B') → h
