To calculate the surface area of a cylinder, you need to find the Base Area (B) and Curved Surface Area (CSA). Therefore, the surface area or the total surface of a cylinder is equal to the sum of the base area times two and the area of the curved surface.

Curved Surface Area- The curved surface area is defined as the area of only curved surface, leaving the circular top and base. Total Surface Area- It is the area of the curved surface as well as the bases. Consider a cylinder having a height ‘h’ and base radius ‘r’.

Since the sphere is a complete curved shape therefore the curved surface area is equal to the total area of sphere. It is also called lateral surface area. Surface Area of Sphere = 4πr², where r is the radius of sphere.

Total surface area of a right circular cone = π(r + l) r. Volume of a right circular cone = 1/3π r2 h.

The surface area of a solid object is a measure of the total area that the surface of the object occupies. Their work led to the development of geometric measure theory, which studies various notions of surface area for irregular objects of any dimension. An important example is the Minkowski content of a surface.

An increased surface area to volume ratio also means increased exposure to the environment. Cells can achieve a high surface area to volume ratio with an elaborately convoluted surface, like the microvilli lining the small intestine. Increased surface area can also lead to biological problems.

Nanoparticles have very large surface area to volume ratios compared to the same material in bulk, as powders, lumps or sheets. For a solid, the smaller its particles, the greater the surface area to volume ratio.

Because surface area is the means by which a solid interacts with its surroundings, be it gas, liquid or other solids. As particle size decreases, the surface area per unit volume (or mass) increases.

Synthetic materials set new world record for greatest amount of surface area. Researchers at Northwestern University, Illinois, have broken a world record in the creation of two synthetic materials, named NU-109 and NU-110, which have the greatest amount of surface areas of any material to date.

Large surface areas means more of something can pass through it at a particular time. In the cells, if the surface area is large then the diffusion rate is very fast in like amoeba and they can easily obtain oxygen and other important molecules due to this adaptation.

Surface Property. Graphene has extremely high specific surface area and high porosity, making them ideal for adsorption of different gases such as hydrogen (H2), methane (CH4), and carbon dioxide (CO2). Theoretical calculations predict a large surface area of single-layer graphene close to 2600 m2 g−1 [66].
