easy · MCQ · Q-02166E

The perpendicular distance of the point P(-3, 5, -7) from the xy-plane is:

  1. A.3 units
  2. B.5 units
  3. C.7 unitsCorrect answer
  4. D.15 units

Solution

The distance of a point (x,y,z)(x,y,z) from the xyxy-plane is ∣z∣|z|. Hence, the required distance is ∣−7∣=7|-7|=7 units.
