a cone...
The length (circumference) of the curved part of a semi-circle is pi times the radius (pi*R). If the diameter is given, then the semi-circle length is 1/2 (pi * x D) because the radius is 1/2 of the diameter.(There are 2pi radians in a full circle.)A closed shape formed from a semi-circle has a perimeter P = D + (pi * D / 2)(diameter plus the curved part)
When you horizontally cut a cylinder, you will see a circle as the resulting 2D shape. This circle is formed by the intersection of the plane (the cut) with the curved surface of the cylinder. The circle will have the same diameter as the base of the cylinder.
The geometric figure formed when two planes intersect is called a polygon.* * * * *Wrong!The correct answer is a straight line.
line
Simply a line is formed......

A Cone.
A cross section of an ellipsoid or sphere. A cone. A [right] truncated paraboloid (like the reflector of a car headlight). There are several others.
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.
