Circular arc hull information

The circular arc hull is a design for boat hulls created by Swedish engineer Fredrik Ljungström. In the 1930s and 1940s Ljungström designed and built sailboats...

perimeter lies inside the convex hull, so the same shape may be also formed as the convex hull of the two remaining circular arcs each spanning an angle of 4π/3...

The circular sector is obtained by unfolding the surface of one nappe of the cone: radius R R = r 2 + h 2 {\displaystyle R={\sqrt {r^{2}+h^{2}}}} arc length...

The Yanmouti sets are defined as the convex hulls of an equilateral triangle together with three circular arcs, centered at the triangle vertices and spanning...
