Frustums
Conical and pyramidal frustums and spherical caps.
Geometry
Conical frustum volume
V = πh(R² + Rr + r²) / 3→GeometryConical frustum lateral area
S = π(R + r)√(h² + (R−r)²)→GeometryPyramidal frustum volume
V = h(S₁ + √(S₁S₂) + S₂) / 3→GeometrySpherical cap volume
V = πh²(3R − h) / 3→GeometryConical frustum total area
Stot=π(R+r)l+π(R²+r²)→GeometryConical frustum slant height
l=√(h²+(R−r)²)→GeometryConical frustum axial section
Sax=(R+r)h→GeometryFrustum properties from radii and height
