The surface area of a sphere is defined as the region covered by its outer surface in three-dimensional space. A Sphere is a three-dimensional solid having a round shape, just like a circle. The formula of total surface area of a sphere in terms of pi (π) is given by:However, when one tries to parametrize the surface of a sphere, the parameters are non-symmetric. For example, using the standard spherical coordinates, the radial angle $\theta$ acts one way (going from 0 to $2\pi$ ), and the azimuth angle $\varphi$ acts a different way (going from 0 to $\pi$ ).Surface Area of a Sphere. The Greek mathematician Archimedes discovered that the surface area of a sphere is the same as the lateral surface area of a cylinder having the same radius as the sphere and a height the length of the diameter of the sphere. The lateral surface area of the cylinder is 2πrh 2 π r h where h = 2r h = 2 r . Surface Area. The surface area of a sphere is the total region covered by its outer surface. It is expressed in square units such as m 2, cm 2, and mm 2. The formula is given below: Surface Area (SA) = 4πr 2, here π = 22/7 = 3.141, r = radius. Let us solve an example to understand the above concept better.The surface area of the sphere can be approximated using the bases of the square pyramids, as nA, where A is the area of each base of the square pyramids used to approximate the sphere, and n is the total number of pyramids used to approximate the sphere. Given that the formula for the surface area of a sphere is 4πr 2, nA ≈ 4πr 2Determine the lateral surface area of the outer cylindrical surface using the formula Ao = 2πroh. Find the lateral surface area of the inner cylindrical surface using the formula Ai = 2πrih. Add all these areas to find the total surface area of the hollow cylinder to get A = 2π ( (ro² - ri²) + roh + rih). Dominik Czernia, PhD.Surface Area. The surface area of a sphere is the total region covered by its outer surface. It is expressed in square units such as m 2, cm 2, and mm 2. The formula is given below: Surface Area (SA) = 4πr 2, here π = 22/7 = 3.141, r = radius. Let us solve an example to understand the above concept better.Formula for surface area of a sphere : S = 4πr 2. Substitute 4 for r. S = 4π (4 2) S = 4π (16) S = 64π in 2. Because 16π ⋅ 4 = 64 π, the surface area of the sphere in part (b) is four times the surface area of the sphere in part (a). So, when the radius of a sphere doubles, the surface area does not double. Using a Great CircleThe biggest circle of a sphere is a circle that has the same centre and radius of a sphere. A great circle of the sphere is a circle that has the same radius and centre as the sphere itself. In this article, let us discuss how to derive the equation of a sphere along with the surface area and the volume of the sphere in detail.

Formula for volume of sphere. The general formula for calculating volume of the sphere is given as follows. Volume of sphere = 4 3 π r 3. In the above formula, the parameters π and r are used. These parameters have the following interpretations. π = 3.142. The value of the radius is half of the sphere diameter. For example,The formula for the volume of a sphere is V = 4/3 π r³, where V = volume and r = radius. The radius of a sphere is half its diameter. So, to calculate the surface area of a sphere given the diameter of the sphere, you can first calculate the radius, then the volume.

Get important Facts by downloading the free PDF. The sphere has the smallest surface area of all surfaces that enclose a given volume, and it encloses the largest volume among all closed surfaces with a given surface area. The sphere therefore appears in nature: for example, bubbles and small water drops are roughly spherical because the surface tension locally minimizes surface area.
