One , What is the generatrix of a cone?
1. The generatrix of a cone is ① the length of the line segment from the vertex of the cone to any point on the circumference of the cone base, ② the generatrix of the cone is The radius of the side-expanded fan.
2. ③The generatrix of the cone is the waist length of the isosceles triangle in the front view and left view of the cone.
2. What is the cone generatrix
1. The cone generatrix Yes: If you cut the side of a right cone, you will get a sector, whose radius is the generatrix of the right cone.
2. Definition 1: The front view of a right cone is an isosceles triangle, and the waist of the triangle is the generatrix of the right cone.
3. Definition 2: The radius of the sector used to form a right cone is called the cone generatrix.
4. Definition 3: The line segment from the vertex of any cone to any point on the base circumference is called the cone generatrix.
3. What is the definition of the busbar of a cone
The busbar refers to : Generating lines of a cylinder, generating lines of a cone, generating lines of a truncated cone Generating lines of a cylinder: Lay the cylinder down (side down) on the table, andThe line segment that touches the table is called the busbar of the cylinder. After cutting the side of the cylinder along the busbar, it unfolds into the busbar of a rectangular cone: place the cone upside down (side down) on the tabletop, and the section that touches the tabletop The line segment is called the busbar of the cone. It can also be said that the side expansion of the cone is a fan shape. Any radius of this fan shape is the busbar of the cone. After cutting the side of the cone along the busbar, it unfolds into a fan shape, a truncated cone. The busbar is similar to the one above.
4. Formula for finding the bus bar of a cone
Surface area of a cone = cone The side area + the area of the base circle where: Side area of the cone = πRL Total area of the cone = πRl + πR2π is pi ≈ 3.14R is the radius of the base circle of the cone L is the generatrix length of the cone (note: it is not a cone) Height) n Cone central angle = r/l*360
5. What is the generatrix of a cone
1. In mathematics, cylinders, cones, spheres, etc. are collectively called bodies of revolution. That is, this type of geometry can be seen to be generated by a line (segment) through rotation, and this line (segment) is called the busbar of the rotating body.
2. For example, a line segment is rotated around its parallel line to generate a cylinder, and this line segment is the generatrix of the cylinder.
3. A line segment rotates around the straight line at one end to generate a cone. This line segment is the generatrix of the cone.
6. What is the cone busbar? Thank you
The answer is: cone The generatrix of a body is the line segment connecting the vertex of the cone to the points on the circle at the base of the cone. is the radius of the sector forming the side of the cone. An infinite number of radii make up the side area of a cone.
OK, this article ends here, I hope it will be helpful to everyone.
