Worked practice questions

The centroid of the tetrahedron with vertices $A(3, -5, 7),\ B(5, 4, 2),\ C(7, -7, -3),\ D(1, 0, 2)$ is:

  1. $(4, -2, 2)$
  2. $(16, -8, 8)$
  3. $(4, -4, 2)$
  4. $(5, -2, 3)$
Show answer and solution

Correct answer: A. $(4, -2, 2)$

$G = (A+B+C+D)/4 = ((3+5+7+1)/4, (-5+4-7+0)/4, (7+2-3+2)/4) = (16/4, -8/4, 8/4) = (4, -2, 2)$.
