Proof of the formula of the surface area of a sphere This video demonstrates that the surface area of a sphere equals the area of 4 circles. (It is not a formal proof) Show Video Lesson The formula for the surface of a sphere is derived by summing up small ring elements of area along...
A = 4 ×π× (d / 2)² = π× d² where d is the sphere diameter. The derivation of this surface area formula requires integration. If you're curious, check out this proof. Surface area of a cylinder To find out the surface area of a cylinder, you should have two values: th...

Some of you may have seen in school that the surface area of a sphere is 4πR24πR2, a suspiciously suggestive formula given that it’s a clean multiple of πR2πR2, the area of a circle with the same radius. But have you ever wondered why is this true? And I don’t just ...
We show that each kind of solution contributes a surface area dependent term to the corresponding asymptotic eigenvalue densities, D E and D H. These surface terms are equal, but have opposite signs. This constitutes a new proof of the well known vanishing of the first order correction of ...
We define the area of such a surface by first approximating the curve with line segments. Revolving a line segment about the x-axis produces the curved surface of a frustum (a cone cut off parallel to its base), the area of which is given by the formula π(R1 + R2)L, where R1 ...
With a growing body of earth-based and spacecraft observational data, and a renewed focus on lunar missions and exploration, the connection between the exospheres and surfaces of planetary bodies is an area of active and growing research, with advances being made on problems such as topographical...

Recently, Ye [39] introduced the Lp geominimal surface area for all −n≠p<1, which extends the classical geominimal surface area (p=1) by Petty and the Lp geominimal surface area (p>1) by Lutwak. In [39], Ye extended the Lp geominimal surface area by his equivalent formula of ...
