It calculates areas and angles, including an 8600 mm² rectangle area result, and determines an arc length using central angles and circle circumference proportions. It then proves angle relationships in circle and congruency/parallelogram diagrams, including a vector-based fraction result K = 2/5. Finally, it solves volume and density for a quarter solid sphere frustum with joined hemisphere, leading to an average density of 3.75 g/cm³, and concludes with an algebraic vectors ratio giving n = 4.
