21. The Census Bureau uses computers to calculate the state centroids and the national centroid. 22. The Census Bureau uses computers to calculate the state centroids and the national centroid . 23. The intersection of the bimedians is the centroid of the vertices of the quadrilateral. 24. The centroid of a tetrahedron is the midpoint between its Monge point and circumcenter. 25. The second is an orthogonal line passing through the centroid of the chosen face. 26. The triangular cross sectional area varies linearly with the vertical height of its centroid . 27. These line segments are divided by the centroid in the ratio 3 : 1. 28. The centroid is the midpoint between its Monge point and circumcenter along this line. 29. Centroids are estimated center points within a zone.30. In the mid-1970s Dziewonski started the Harvard Global Centroid Moment Tensor Catalog.
