  2. Cone - Wikipedia

    en.wikipedia.org/wiki/Cone

    In modern mathematics, this formula can easily be computed using calculus — it is, up to scaling, the integral = Without using calculus, the formula can be proven by comparing the cone to a pyramid and applying Cavalieri's principle – specifically, comparing the cone to a (vertically scaled) right square pyramid, which forms one third of a ...

  3. File:Visual proof cone volume.svg - Wikipedia

    en.wikipedia.org/wiki/File:Visual_proof_cone...

    1. A cone and a cylinder have radius r and height h. 2. Their volume ratio is maintained when the height is scaled to h' = r √Π. 3. The cone is decomposed into thin slices. 4. Each slice is transformed into a square of side h' using Cavalieri's principle. 5. The pyramid is replicated twice. 6. Combining them into a cube shows that the volume ...

  4. Hypercone - Wikipedia

    en.wikipedia.org/wiki/Hypercone

    In geometry, a hypercone (or spherical cone) is the figure in the 4-dimensional Euclidean space represented by the equation x 2 + y 2 + z 2 − w 2 = 0. {\displaystyle x^{2}+y^{2}+z^{2}-w^{2}=0.} It is a quadric surface, and is one of the possible 3- manifolds which are 4-dimensional equivalents of the conical surface in 3 dimensions.

  5. The Method of Mechanical Theorems - Wikipedia

    en.wikipedia.org/wiki/The_Method_of_Mechanical...

    The condition of balance ensures that the volume of the cone plus the volume of the sphere is equal to the volume of the cylinder. The volume of the cylinder is the cross section area, times the height, which is 2, or . Archimedes could also find the volume of the cone using the mechanical method, since, in modern terms, the integral involved ...

  6. Tree volume measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_volume_measurement

    The value 75.4 = 24 π, where 24 π substitutes for factor of 12 π in the formula for a volume of frustum of a cone encompassing a full tree using one base circumference, converting it to a volume formula that uses a basal circumference that is the average of circumferences C 1 and C 2.

  7. Bicone - Wikipedia

    en.wikipedia.org/wiki/Bicone

    For a circular bicone with radius R and height center-to-top H, the formula for volume becomes V = 2 3 π R 2 H . {\displaystyle V={\frac {2}{3}}\pi R^{2}H.} For a right circular cone, the surface area is

  9. Pappus's centroid theorem - Wikipedia

    en.wikipedia.org/wiki/Pappus's_centroid_theorem

    The theorem applied to an open cylinder, cone and a sphere to obtain their surface areas. The centroids are at a distance a (in red) from the axis of rotation.. In mathematics, Pappus's centroid theorem (also known as the Guldinus theorem, Pappus–Guldinus theorem or Pappus's theorem) is either of two related theorems dealing with the surface areas and volumes of surfaces and solids of ...
