For a circular cone with radius r and height h, the base is a circle of area and so the formula for volume becomes [6] V = 1 3 π r 2 h . {\displaystyle V={\frac {1}{3}}\pi r^{2}h.} Slant height
the alternative formula is therefore: = (+ +). Heron of Alexandria is noted for deriving this formula, and with it, encountering the imaginary unit: the square root of negative one. [4] In particular: The volume of a circular cone frustum is:

While this formula is more involved than the equivalent for a circle, if the major and minor axes of each ellipse are equal, the result is the more familiar formula for the frustum of a right circular cone. [citation needed] The volume calculations for these individual frustums of trunk segments can be further refined by considering the overall ...
Cone: Tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex: A right circular cone and an oblique circular cone Cylinder: Straight parallel sides and a circular or oval cross section A solid elliptic cylinder A right and an oblique circular cylinder Ellipsoid
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
An example of a spherical cap in blue (and another in red) In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane.It is also a spherical segment of one base, i.e., bounded by a single plane.
