What is the cross section 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.
Whats the definition of cross section?
Definition of cross section 1a : a cutting or piece of something cut off at right angles to an axis also : a representation of such a cutting. b : section sense 3b. 2 : a measure of the probability of an encounter between particles such as will result in a specified effect (such as scattering or capture)
Which is the best definition for cross section?
The definition of a cross section is a section of something that has been cut down the middle to show what is inside. An example of a cross section is what you see on the inside when you cut a layered sandwich in half. noun. 1.
What is a cross section of a 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 find the cross section of a sphere?
A cross-section of a sphere is just a circle, so you would use the equation A=(pi)*r^2, where r is the radius of the circle created by the cross section.
What is the purpose of cross section?
Cross sections are a power tool that ensures high quality production and products. Preparation of a cross section is a destructive process, a section of the production panel is cut out, in most cases a specially designed Test coupon is used (these are placed on every panel).
What is a cross section in architecture?
A cross section, also simply called a section, represents a vertical plane cut through the object, in the same way as a floor plan is a horizontal section viewed from the top. A sectional elevation is a combination of a cross section, with elevations of other parts of the building seen beyond the section plane.
What are cross sections used for?
A cross section is the shape that you create when you cut through or make a slice of an object. They allow us to see what’s inside an object. Some of the most famous cross sections are conic sections, cross sections are created by slicing a right cone in various ways.
What is a cross section in a prism?
A cross section is the intersection of a plane and a three dimensional figure. A rectangular prism can have several different types of cross sections. If the cross section is perpendicular to the base, it will be the same as the lateral faces (for a rectangular prism).
How are cross sections used in real life?
Cross sections are used in architecture and engineering quite often. By understanding cross sections and how to cut a certain object to create the desired shape, we are able to construct amazing buildings and other inventions. Another common example of cross sections are the cross sections created when sawing wood.
What are all the the cross sections of a sphere?
All cross sections of a sphere are circles. (All circles are similar to one another.) If two planes are equidistant from the center of a sphere, and intersecting the sphere, the intersected circles are congruent. • A great circle is the largest circle that can be drawn on a sphere.
What is the cross sectional area of a sphere?
The distance from the center to the surface of the sphere is called its radius. Any cross-section of a sphere is a circle. If r is the radius of a sphere, the volume V of the sphere is given by the formula V = 4/3 × pi × r3. The surface area S of the sphere is given by the formula S = 4 × pi × r2.
What is the shape of a cross section?
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.
What is a section of a sphere?
In geometry, a spherical sector is a portion of a sphere defined by a conical boundary with apex at the center of the sphere. It can be described as the union of a spherical cap and the cone formed by the center of the sphere and the base of the cap.
