# What are all cross sections of a sphere?

## What are all cross sections of a sphere?

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

### Can an ellipse be a cross section of a sphere?

ANSWER: No, the cross section of a sphere is always a circle, not an ellipse.

What shapes can cross sections be?

Possible cross sections are circles (cut parallel to the circular base), ellipses (cut at an angle, not parallel to the circular base and not intersecting the base of the cone), parabolas (cut parallel to the edge of the cone, not intersecting the vertex but intersecting the base), and hyperbolas (cut perpendicular to …

Can a sphere have a cross section that is a line segment?

A cross section is two-dimensional. When a plane intersects a solid figure, the cross sectional face may be a point, a line segment, or a two-dimensional shape such as, but not limited to, a circle, rectangle, oval, or hexagon. Point. The plane is tangent to the sphere, intersecting in only one point.

## What is the cross section of a circle?

The cross-sectional area of a cylinder is equal to the area of a circle if cut parallel to the circular base. 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.

### How do you find cross sections?

A cross section is the shape we get when cutting straight through an object. The cross section of this object is a triangle. It is like a view into the inside of something made by cutting through it. This is a cross-section of a piece of celery.

Can a cross section be 3d?

When we slice a three-dimensional object, we expose new faces that are two dimensional. The two-dimensional face is a cross section. Many different cross sections are possible when slicing the same three-dimensional object.

Can a cylinder have an oval cross section?

The cross-section of a cylinder is an ellipse – sam.

## What are all of the different possible cross sections that can be made from a solid cube?

Cross sections of a cube

• a single point (a vertex of the cube)
• a line segment (an edge of the cube)
• a triangle (if three adjacent faces of the cube are intersected)
• a parallelogram (if two pairs of opposite faces are intersected – this includes a rhombus or rectangle)
• a trapezium (if two pairs of.

### How many cross sections can a cone have?

There are three other cross sections — a point, a line, and a pair of intersecting lines.

What is the cross-section of a circle?

What is a cross-section of a 3D shape?

A cross-section is a plane section that is a section of a three-dimensional object that is parallel to one of its planes of symmetry or perpendicular to one of its lines of symmetry. Describe shapes formed by cross-sections (square, rectangle, triangle, etc).

## How do you calculate cross section?

How to Calculate Cross Section Area. If the shape is rectangular, measure the width and length of the rectangle. Calculate the cross-sectional area by determining the area of the geometric shape. For a rectangle, multiply adjacent side lengths using this formula: area = length x width. For a circle, the area = (3.14) x radius x radius.

### What shape are the cross sections of a sphere?

The cross section of an object therefore represents an infinitesimal “slice” of a solid, and may be different depending on the orientation of the slicing plane. While the cross section of a sphere is always a disk, the cross section of a cube may be a square, hexagon, or other shape.

What are the types of cross sections?

There are two major classes of cross sections used in understanding petroleum reservoirs. Structural cross sections, which show the present day geometry of an area. Stratigraphic cross sections, which show prior geometric relationships by adjusting the elevation of geological units to some chosen geological horizon (Figure 1).

What is the cross sectional area of a sphere?

Cross-Sectional Area of a Sphere Any theoretical plane placed through a sphere will result in a circle (think about this for a few moments). If you know either the diameter or the circumference of the circle the cross-section forms, you can use the relationships C = 2πr and A = πr 2 to obtain a solution.
