A Cone
A cone. It has a circle for the base, and a curved face tapering to a point.
Semi Circle
There cannot be such a shape. It is not a cylinder because a cylinder sdoes not have a rectangular face. A rectangle must be a flat face and the only flat faces in a cylinder are the circle faces. The curved face can be "opened out" into a rectangular shape but because the face is curved it cannot be rectangular.
It could be a semi-sphere but mostly it's a cone.
