Maths question what is a cylinder?
A cylinder is also known as a circular prism because its flat faces and cross-sections are circular. It is called a prism because it is a 3-Dimensional object.
How are a cylinder and a triangular prism different?
Both are prisms. A prism is a 3D shape which has a uniform cross section, so anywhere along it's length where you take a slice you always see the same shape. To say which prism you mean we add the name of this cross section 'triangular prism', 'hexagonal prism' etc. We have a special name for a circular prism - a cylinder. Also, a rectangular prism is a cuboid.
What is the same of a cylinder and rectangular prism?
Cylinders are like rectangular prisms because cylinders are also prisms. A cylinder is a circular prism. It's like squeezing toothpaste out of the tube. Take the cap off your toothpaste and make sure the toothpaste is neatly flat. Then squeeze a bit out and cut that off neatly. You have a little piece of stuff that is a circular prism in shape, or a cylinder. A prism has to have two flat ends, both the same shape, and between the two ends the sides have to be straight from one end to the other. A new pencil which has no sharpened end is usually a cylinder or a hexagonal prism. They make pencils these days that are triangular prisms. Kids learning to hold a pencil properly use them because they fit neatly in the thumb and the first two fingers.
When is a face of a three-dimensional figure also a cross-section of that same figure?
When the 3-d shape is a prism and the cross section is in a plane at right angles to the length of the prism.
What is the surface area of a right prism?
The surface area of a right prism is the sum of the areas of all its faces. The formula for calculating the surface area of a right prism is 2 × (base area) + (lateral area), where the base area is the area of the base shape and the lateral area is the sum of the areas of the remaining faces. The lateral area can also be calculated by multiplying the perimeter of the base shape by the height of the prism.
If a circular prism is called a cylinder does an oval prism have a special name too?
No, it is also a cylinder.
What properties does a 3d cylinder have?
it has 3 faces and its also a prism.

The figure formed by the intersection of a solid with a plane parallel to the base of the solid is congruent to the base if the solid is a?
The answer would be a right cylinder. A right cylinder is a cylinder that has a closed circular surface having two parallel bases on both the ends and whose elements are perpendicular to its base.
What is a six faced prism called?
A square cuboid, see below form more details. A right rectangular prism is also called a cuboid, it has 6 faces. A right square prism is simply a square box, and may also be called a square cuboid.
How is car engine classified?
A car engine can be classified based on the number of cylinders it has. It could be a 4 cylinder, 6 cylinder, 8 cylinder, 10 cylinder, or 12 cylinder (the last two engines are mainly used in exotic cars). There are also rotary engines, electric engines, natural gas engines and hybrid (electric/gas) engines. Each of these has subcategories as in the most common piston engines listed above.
What shape is a quadrangle with 2 pairs of congruent adjacent sides?
It is a rhombus. If the sides form right angels, it can also be classified as a square. It is a rhombus. If the sides form right angels, it can also be classified as a square. It's a rhombus.

What is the meaning of cylinder?
A cylinder is a three-dimensional geometric shape with two parallel circular bases connected by a curved surface. It can also refer to a device that contains or compresses something in the shape of a cylinder, such as an engine cylinder or a gas cylinder.
