Slant height - Citizendia

The slant height of a right circular cone is the distance from any point on the circle to the apex of the cone. A cone is a three-dimensional Geometric shape that tapers smoothly from a flat round base to a point called the apex or vertex Circles are simple Shapes of Euclidean geometry consisting of those points in a plane which are at a constant Distance, called the

The slant height of a cone is given by the formula $\sqrt{r^2+h^2}$ , where $r$ is the radius of the circle and $h$ is the height from the center of the circle to the apex of the cone.

It is trivial to see why this formula holds true. If a right triangle is inscribed inside the cone, with one leg of the triangle being the line segment from the center of the circle to its radius, and the second leg of the triangle being from the apex of the cone to the center of the circle, then one leg will have length $h$ , another leg will have length $r$ , and by the Pythagorean theorem, $r 2 + h 2 = d 2$ , and $d=\sqrt{r^2+h^2}$ gives the length of the circle to the apex of the cone. Two types of special right triangles appear commonly in geometry the "angle based" and the "side based" (or Pythagorean Triangles The former are characterised In Geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its end points In Mathematics, the Pythagorean theorem ( American English) or Pythagoras' theorem ( British English) is a relation in Euclidean geometry
