a cone has 2 surfaces
Surfaces: 2 (the base and the slanted surface)
Edges: 1 (the joining of base with the slanted surface)
Corners: 1 (the apex)
Mathematically, a cone is infinite and so has no flat surface. The popular cone is actually a truncated cone and does have 1 flat surface.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
This cone has a lateral surface area of approximately 226.73cm2
no
No but a cone has a curved surface
Mathematically, a cone is infinite and so has no flat surface. The popular cone is actually a truncated cone and does have 1 flat surface.
A cone has one curved surface.
2
Its base is a flat surface
It has just the one curved surface area and and its base
two
A cone has 1 flat surface, because a cone has 1 corner and has 4 edges. The reason that is is because a cone is round. A cone has a flat surface at the bottom of the cone. The reason it is because the cone doesn't have any vertices and most of the solid and plane figures have vertices.
None. A cone has an apex or vertex, a lateral surface and a base.
Just one at the base, the rest is a curved surface
Infinitely many. There are infinitely many lines from the apex to the base. Every point on each of these lines is on the surface of the cone.
None. A cone is a surface of revolution and thus it has no flat sides. Polygons are planar figures. A cone has no planar faces.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique cone.
