Spherical area
WebSpherical trigonometryis the branch of spherical geometrythat deals with the metrical relationships between the sidesand anglesof spherical triangles, traditionally expressed using trigonometric functions. On the sphere, geodesicsare great circles. Spherical trigonometry is of great importance for calculations in astronomy, geodesy, and navigation. http://math.ucla.edu/~robjohn/math/spheretrig.pdf

WebMar 26, 2024 · Method 1 is consistent with approximating the area of a thin ring $2πR^2sin(θ)dθ$, which you can check by integration. But I think the formula for spherical cap area is usually obtained by integration, so this is some sort of circular reasoning. Method 2 is incorrect. WebJan 11, 2024 · A sphere is a perfectly round geometrical 3D object. The formula for its volume equals: volume = (4/3) × π × r³ Usually, you don't know the radius - but you can measure the circumference of the sphere instead, e.g., using the string or rope. The sphere circumference is the one-dimensional distance around the sphere at its widest point.
