## What shape can be the cross-section of a cylinder by horizontally?

circle

The vertical cross-section of a cylinder is a rectangle, and the horizontal cross-section is a circle.

**What is a horizontal cross-section?**

The horizontal cross-section also known as parallel cross-section is when a plane cuts a solid shape in the horizontal direction such that it creates a parallel cross-section with the base. For example, the horizontal cross-section of a cylinder is a circle.

**What is the cross-sectional area of a shape?**

The cross-sectional area is the area of a two-dimensional shape that is obtained when a three-dimensional object – such as a cylinder – is sliced perpendicular to some specified axis at a point. For example, the cross-section of a cylinder – when sliced parallel to its base – is a circle.

### What Cannot be a cross section of a cylinder?

SOLUTION: A plane at an angle relative to the bases that does not intersect either base will intersect only the lateral face of the cylinder. Since it is not parallel to either base, and does not intersect either base, the shape of the cross section must be an ellipse.

**What is the cross sectional area of a hollow cylinder?**

The inner curved surface area = 2πr × Height, the outer curved surface area = 2πR × Height. Solved Examples on Hollow Cylinder: A hollow copper pipe of inner radius 3 cm and outer radius 4 cm is melted and changed into a solid right circular cylinder of the same length as that of the pipe.

**What shape Cannot be a cross section of a cylinder?**

#### Which could be the shape of the cylinder?

A cylinder has two flat ends in the shape of circles. These two faces are connected by a curved face that looks like a tube. If you make a flat net for a cylinder, it looks like a rectangle with a circle attached at each end.

**What is the area of the cylinder?**

A cylinder’s volume is π r² h, and its surface area is 2π r h + 2π r².

**How do you find the area of a cross shape?**

And how do i get the coordinate points on the shapes and coordinate points in shape? The area of the cross can be calculated as follows: Area(horizontal bar) + Area(vertical bar) – Area(intersection between the horizontal bar and the vertical bar).

## What is the hollow cylinder?

A hollow cylinder is a cylinder that is empty from the inside and has some difference between the internal and external radius. In other words, it is a cylinder that is empty from the inside and has some thickness at the peripheral.

**How are the shapes of a cone congruent?**

‘The shapes of the horizontal cross-sections of the cone are all congruent’. Now, if we cut the cone horizontally, the cross-sectional shape is a ‘circle’. Further, the radius of the circle vary depending on the position form where the cone is cut i.e. If cut from the top, the circle is approximately equal to a point.

**How is the cross sectional shape of a cone determined?**

Now, if we cut the cone horizontally, the cross-sectional shape is a ‘circle’. Further, the radius of the circle vary depending on the position form where the cone is cut i.e. If cut from the top, the circle is approximately equal to a point. If cut from the middle, the radius of the circle is less than the radius of the cone.

### Is it true that two figures are congruent if they overlap each other?

Now, ‘two figures are congruent if they overlap each other’. Since, the circles have different radius, they will not overlap each other. Thus, all the cross-sections of the cone would not be congruent. Hence, the given statement is false.
