heap_volume_cone — DRIVE `granular` op

• Data kinds: scalar × scalar → table

• Call: import fullseye as fs; fs.ledger.heap_volume_cone(R: 'float | None' = None, H: 'float | None' = None, phi_deg: 'float | None' = None) -> 'dict' (to call the implementation directly, import granular; granular.heap_volume_cone(R: 'float | None' = None, H: 'float | None' = None, phi_deg: 'float | None' = None) -> 'dict'; from the registry, opsdrive.get("heap_volume_cone"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

円錐の山の閉形式 —— `R・H・phi_deg` のうち ちょうど 2 つ を与えると残りと体積を返す。

`V = (π/3) R² H、H = R tan φ。返り: R, H, phi_deg, V [m³]、A`(底面積 πR²)。

Raises `ValueError`: 与えた数が 2 つでない、または ≤ 0 / 非有限 / 角が (0, 90) の外。

3 つ全部渡されたときも拒否する(矛盾した 3 つ組を黙って片方で上書きしない)。
