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.
The surface area is 4 Ï r 2 for the sphere, and 6 Ï r 2 for the cylinder (including its two bases), where r is the radius of the sphere and cylinder. The sphere has a volume two-thirds that of the circumscribed cylinder. Similarly, the sphere has an area two-thirds that of the cylinder (including the bases).
