Throat Cancer Symptoms. Most often, throat cancer symptoms are mistaken with the symptoms of other diseases. Throat Cancer is also called as Larynx cancer, Vocal cord cancer or Cancer of the glottis. Throat cancer is a specific type of cancer of the vocal cords, voice box (larynx), or other areas of the throat.
Example 1: Find the lateral surface area of a cylinder with a base radius of 3 inches and a height of 9 inches. L. S. A. = 2 Ï (3)(9) = 54 Ï inches 2. â 169.64 inches 2. The general formula for the total surface area of a cylinder is T. S. A. = 2 Ï rh + 2 Ï r 2.
A cylinder whose cross section is an ellipse, parabola, or hyperbola is called an elliptic cylinder, parabolic cylinder, or hyperbolic cylinder respectively. An elliptic cylinder with the half-axes a and b for the surface ellipse and the height h.An elliptic cylinder is a quadric surface, with the following equation in Cartesian coordinates : This equation is for an elliptic cylinder, a generalization of the ordinary, circular cylinder (a = b).here d is the diameter. For a given volume, the closed cylinder with the smallest surface area has h = 2r. Equivalently, for a given surface area, the closed cylinder with the largest volume has h = 2r, i.e. the cylinder fits snugly in a cube (height = diameter).
