If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. h is the height of a cylinder. Finally, the total surface area of the cylinder formula is simply the sum of the base surface area and the lateral surface area: total_area = base_area + lateral_area, or total_area = 2 * π * r² + (2 * π * r) * h, or total_area = 2 * π * r * (r + h). It is basically equal to the sum of area of two circular bases and curved surface area. The width is the height h of the cylinder Total Surface Area = Lateral Surface Area + Area of bases = 2πrh + 2πr² = 2πr (h+r) Another aspect of cylinders that we must learn is that of a hollow cylinder, like a pipe for example. See the image below. A cylinder is a 3D shape with a circular cross-section and a curved surface. The area formula is really the formula for the curved surface (that is the 2 π r h portion) added to the area of both ends (that is the 2 π r 2 portion). The total surface Sometimes you may be required to calculate the total surface area of a hollow cylinder or tube. The total surface area ( TSA) of a cylinder with radius r and height h is given by. Hence, the total surface area of the cylinder = 2πrh + 2πr²=2πr(h+r).
