1 Problem and Resolution Question Set the height of the cylinder to be 2, the radius of the bottom surface to be 1, and use a plane to cut it into two geometric shapes with the same shape, as shown in the figure on the right. Expand the side of one of the geometry and expand the image on the side. Yes () (A) (B) (C) (D) (2005 Hefei High School mathematics test questions) This question is for students who have a solid foundation in mathematics. They can rely on mathematical awareness, combined with spatial imagination and logical analysis. Made
