What is the development of lateral surface of a cone?
What is the development of lateral surface of a cone?
The correct option is “C”. “When the curved surface of a cone is opened and laid on a plane, it shows the shape of a sector. The radius of the sector will be equal to the slant height of the cone. The length of the arc will be equal to the circumference of the base of the cone, i.e. 2πr.
Which method is used for development of lateral surface?
Parallel-line Method: It is used for developing prisms and single curved surfaces like cylinders, in which all the edges/generation of lateral surfaces are parallel in each other.
What is development of lateral surfaces of solids?
DEVELOPMENTS. • A layout of the complete surface of an object is. called a development or pattern. • The layout of only the sides without the top or. bottom is called the lateral surface.
What is meant by development of surfaces?
“The development of surface of an object means the unrolling and unfolding of all surfaces of the. object on a plane.” “If the surface of a solid is laid out on a plain surface, the shape thus obtained is called the.
What is the principle of development of surfaces?
The development of surface of an object means the unrolling or unfolding of all surfaces of the object on a plane. Principle of development: Every line on the development should show the true length of the corresponding line on the surface which is developed.
What method is used for development of right cone?
Radial line method: This method is used for pyramids and single curved surfaces like cones in which the apex is taken as a center and its slant edges or generator as the radius for its development.
What are different methods of development of surfaces?
Every line on the development should show the true length of the corresponding line on the surface which is developed. Parallel-line Method: It is used for developing prisms and single curved surfaces like cylinders, in which all the edges/generation of lateral surfaces are parallel in each other.
What are the different methods of development of surfaces?
Methods of development of surfaces are:
- ➢ Parallel line development.
- ➢ Radial line development.
- ➢ Triangulation development.
- ➢ Approximate development.
What is the meaning of lateral surface area?
The lateral surface of an object is all of the sides of the object, excluding its base and top (when they exist). The lateral surface area is the area of the lateral surface. This is to be distinguished from the total surface area, which is the lateral surface area together with the areas of the base and top.
Why the development of surfaces is needed?
Surface development is the process of mapping a given 3D surface into a 2D shape. The usual objective is to achieve this mapping while preserving isometry, or, for non-developable surfaces, to minimize the distortion.
