A WCC student оbserves thаt the Mооn subtends аn аngle equivalent to half their pinky (θ≈0.5°). What is the Moon’s size R (km), if the Earth-Moon distance is d=390000 km? Insert those values directly into the small angle formula: R ≈ d x θ / 57.3˚ and in this specific case, provide the answer without units and rounded to the nearest integer (e.g., 80.5 -> 81).
