A riddle is: I am a polyhedron I have two surfaces one of my surfaces is formed by a circle the other face is curved what am I?
A circle
A Circle.
If you're talking about the 4th grade Study Link 11.3 "Geometry Riddles" these are the answers: 1. I am a geometric solid. I have two surfaces. One of my surfaces is formed by a circle. The other surface is curved. What am I? Answer: Cone 2. I am a geometric solid. I have one square base. I have four triangular faces. Some Egyptian pharaohs were buried in tombs shaped like me. What am I? Answer: Square Pyramid 3. I am a polyhedron...( it's taking to long to type I'm going to just right the answers now) Answer: Hexagonal Prism 4. Answer: Octahedron Umm... those are the answers...bye!
A solid figure with 2 flat surfaces and 0 vertices is a cylinder. A cylinder has two circular flat surfaces, known as bases, and no vertices because it does not have any corners or points where edges meet. It is a three-dimensional shape that is formed by a curved surface connecting the two bases.
When in reference to architecture, arris refers to the sharp edge formed when two curved or flat surfaces meet. The surfaces must meet at a salient angle.
A cardioid is a type of geometrical shape that is a type of limacon. A cardioid is formed when a circle is rolled around another circle creating a curved shape.
