Answering Questions About Using a Sector to Form a Cone
The surface of a cone can be parameterized as. f(θ,h)=(hcosθ,hsinθ,h),{\displaystyle f(\theta ,h)=(h\cos \theta ,h\sin \theta ,h),} where θ∈[0,2π){\displaystyle \theta \in [0,2\pi )}is the angle "around" the cone, and h∈R{\displaystyle h\in \mathbb {R} }is the "height" along the cone. See more A cone is a three-dimensional geometric shape that tapers smoothly from a flat base (frequently, though not necessarily, circular) to a point called the apex or vertex. A cone is formed by a set of line segments, half-lines See more In projective geometry, a cylinder is simply a cone whose apex is at infinity. Intuitively, if one keeps the base fixed and takes the limit as the apex goes to infinity, one obtains a cylinder, the angle of the side increasing as arctan, in the limit forming a right angle. … See more • Weisstein, Eric W. "Cone". MathWorld. • Weisstein, Eric W. "Double Cone". MathWorld. • Weisstein, Eric W. "Generalized Cone". MathWorld. See more The perimeter of the base of a cone is called the "directrix", and each of the line segments between the directrix and apex is a "generatrix" or … See more Volume The volume $${\displaystyle V}$$ of any conic solid is one third of the product of the area of the base See more The definition of a cone may be extended to higher dimensions; see convex cone. In this case, one says that a convex set C in the real vector space R is a cone (with apex at the origin) if for … See more • Bicone • Cone (linear algebra) • Cylinder (geometry) • Democritus • Generalized conic • Hyperboloid See more Web1 Answer. Let's consider a sector lying flat, with a missing central angle of α 0. If we now linearly (with respect to angle) draw this missing sector closed, then α ( t) = α 0 − d α d t t is the missing sector angle when viewing the rising cone from above, on-axis. Let α ( 1) = 0 (when t = 1, we make the final cone), so α ( t) = α 0 ... Web1 The radius of the sector is the lateral height $l$ of the cone, and the length of the arc is the circumference of the base, that is, $2\pi r$. So the angle you ask for is $$\theta=\frac {2\pi r} {2\pi l}=\frac rl$$ measured in … king expedited services
