What 2D shapes make up a sphere and a cone?
Answer (2)
Cone: A cone has a curved face and a flat face. The flat face is a circle, the curved face is a curved triangle. A sphere just has one curved face, which you cannot obtain from a 2D shape. The sphere is a ball and has the crosssection of a circle, which is a round shape with one side and no corners.
A cone consists of a circle as its flat base and a curved triangle as its lateral surface, while a sphere has a single continuous curved surface with a circle as its cross-section when sliced. Therefore, a cone is formed from two 2D shapes, while a sphere is associated with one 2D shape. The primary 2D shape for both is the circle.
