Cylinder diagonal calculator

Diagonal in geometry, a line segment connecting two non-adjacent vertices of a polygon or polyhedron. The diagonal of a polygon is a line segment connecting its two vertices that do not lie on one side.

A cylinder is a geometric body that is bounded by a cylindrical surface and 2 planes that are parallel and intersect.

The diagonal of the cylinder connects the opposite points of the diameters of the circles that serve as the bases. In order to find the diagonal of the cylinder, it is necessary to draw the diameter of the lower base from the top of the diagonal and the height of the cylinder from the top of the diagonal. These segments together give a right triangle in the inner space of the cylinder, from which by the Pythagorean theorem one can find the diagonal of the cylinder. The legs of the triangle are the height h and the diameter D, and the diagonal of the cylinder d will be the hypotenuse.
