A sphere of radius r has surface area 4πr 2.. The surface area (symbol A) of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat ...
Mar 18, 2024 · Surface area of a cylinder: A = 2πr² + 2πrh, where r is the radius and h is the height of the cylinder. Surface area of a cone: A = πr² + πr√(r² + h²), where r is the radius and h is the height of the cone. Surface area of a rectangular prism (box): A = 2(ab + bc + ac), where a, b and c are the lengths of three sides of the cuboid.
The surface area of a closed cylinder can be calculated by summing the total areas of its base and lateral surface: base SA = 2πr 2. lateral SA = 2πrh. total SA = 2πr (r + h) where r is the radius and h is the height. Jeremy has a large cylindrical fish tank that he bathes in because he doesn't like showers or bathtubs.
Surface area of a box. The surface area formula for a rectangular box is 2 x (height x width + width x length + height x length), as seen in the figure below:. Since a rectangular box or tank has opposite sides which are equal, we calculate each unique side's area, then add them up together, and finally multiply by two to find the total surface area.
