Cone
A cone is a three-dimensional figure with a circular base lying in one plane plus a vertex not lying on that plane. The remaining surfaces of the cone is formed by joining the vertex to points on the circle by line segments.

This scene in Harry Potter and the Prisoner of Askaban takes place when Harry, Ron, and Hermione are watching the Minister of Magic, Dumbledore, and the executioner of Buckbeak enter Hagrid's hut while they are trying to escape through Hagrid's back door. The cone is the top of the small house that Hagrid keeps for his animals.
"Slowly, in a kind of horrified trance, Harry, Ron, and Hermione set off silently around Hagrid's house. As they reached the other side, the front door closed with a sharp snap." -Harry Potter and the Prisoner of Azkaban, Page 330

This scene in Harry Potter and the Prisoner of Askaban takes place when Harry, Ron, and Hermione are walking down the stone steps on their way to Hagrid's hut, after they receive the news of Buckbeak's execution. The tall towers on Hogwarts Castle are cones.
"Walking very close together so that nobody could see them, they crossed the hall on tiptoe, then walked down the stone front steps into the grounds." -Harry Potter and the Prisoner of Azkaban, Page 327
