Finding volume of a cone using its cross section using …
Area of the cross section = $pi (s)^2 = pi r^2 (1 - frac{x}{h})^2$ Using this information of the area of cross section, integrate $int_0^h (pi r^2 (1 - frac{x}{h})^2) dx$ This integration does not give me the volume of the cone: $frac{1}{3} pi r^2 h$ Next, the volume of the cone could also be $frac{1}{3} pi r^2 h sin theta$

How to calculate the scattering corss-section of a gold
The scattering cross section as a function of wavelength was calculated by integrating the dot product of the scattered intensity vector and the normal vector pointing outwards from the particle surface across the entire particle surface. The extinction cross section was calculated by summing the absorption and scattering cross sections.

Calculating ultimate pit limits and determining pushbacks in …
The floating cone or inverted cone method examines each ore block, in descending order, to determine which blocks in the cone would have to be removed to mine that block. If the sum of the revenue exceeds the costs when that cone is mined, then that cone is removed from the block database ( Fig. 2 ).

The vertical cross section of a cone is a triangle. Suggest Corrections. 4. Similar questions. Q. Which of the following is the vertical cross section of a cone ? Q. Name the cross section when a cone is cut vertically. Q. Which of the following is the horizontal cross section of a cone?
Cross section
The cross section formed by the intersection of a plane that is parallel to the base of a regular triangular prism is an equilateral triangle. When a plane intersects a cone at different angles or positions, one of four cross-sectional shapes is formed. Plane. 2D. 2D shapes. Cross section. Intersecting planes.

All the Cross-Sections of a Cone
Cone cross-sections are obtained when we cut a cone with a plane. We can obtain different cross-sections depending on the orientation of the plane. It is possible to obtain circular, elliptical, parabolic, and hyperbolic cross-sections. Here, we will learn about each of the cross-sections of a cone using diagrams.
