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.
no
This cone has a lateral surface area of approximately 226.73cm2
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.
Just one at the base, the rest is a curved surface
None. A cone has an apex or vertex, a lateral surface and a base.
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.
False. The surface area formula for a right cone is not the same as the surface area formula for an oblique 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.
