We present visual proofs for the lateral surface area of a frustum of a right circular cone by relating the unwrapped surface to a rectangle.doi:10.4169/college.math.j.47.5.346Miyeon KwonMathematical Association of AmericaCollege Mathematics Journal...
Therefore, the anomaly distribution at slots is different from that of the hole features. The occurrence rate of defects at blade slots per unit area and the size data of the defects are the critical data to establish the anomaly distribution. Show moreView article The underlying mechanisms 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 ...
the increase of the Λ also results in a decline of the underwater aerophilicity of the PTFE surface. The fall of the in-air hydrophobicity and underwater aerophilicity is due to the fact that the area fraction of the laser-induced microstructures t...
On the other hand, the higher surface area of structure 70–70–8 results in a higher friction during the demoulding, which might cause deformation or even fracture of the moulded polymer cones44. Interestingly, the water wettability of the two samples however follows the trend of their silicon...

Proof. We will sketch the proof for a set of bivariate surface patches in ℝd satisfying Assumptions (A1)–(A5) with s = 2, i.e., a triple of surface patches intersect in at most two points. For a pair of surface patches γi,γj∈ Γ, let βij denote the intersection arc γ...
where A1 and A2 are the areas of strips of orientation n1 and n2, respectively, while A is the area of the sum of these areas projected onto the plane bounded by the dashed lines in the figure. This behavior, again, is consistent with the identification of the misorientation as a density...
