it has one more, because a cylinder has 2 and a cone has one.
A cylinder and a cone have infinitely many planes of symmetry because of the circular face. However, a cylinder can also be cut in half lengthwise (imaging cutting a soda can in half), while a cone cannot (imagine cutting a ice cream cone in half). Therefore, a cylinder has one more plane of symmetry than a cone.
Cone shaped
Most types of volcanoes are either crater shaped or cone shaped. Stratovolcanoes are shaped like tall cone mountains and shield volcanoes are more flat and spread out.
A cylinder is stronger and has more surface area.
It isn't. If the cylinder and the cone have the same height and radius, the cylinder has a larger volume (twice as large). If they do not have the same height and radius you need more information to prove their relative volumes.
CONE
The volume of a cylinder is three times as much.
because since a cone is large on the bottom and tapers to a point on the top, so does the volume of an object. if the graduate is cone shaped the lines would be closer at the bottom and more spread out at the top because any given crossection of the bottom would have more volume than one further up.
Traffic cones are orange because it makes them stick out more, making them easier to notice.
Cone shaped deposits that rise from the floor of a cave are called Stalagmites. This is easy to remember as it contains a letter 'G' as does ground. While a Stalactite, which hangs down from a cave ceiling, contains a letter 'C.'
Because 2Pi x r x L is the curved surface of a cylinder. Clearly a cylinder have more surface area than a cone of same height and radius. The surface of the cone is Pi x r x S where S is the slope length, so the cylinder has approximately double the surface area (note S is longer than L).
