Question

Find the distance of the point P from the origin:

• A.
  3
• B.
  2
• C. $\sqrt{14}$
• D.
  6

Answer 1

The correct option is C $\sqrt{14}$

The coordinates of the point P are (2,3,1). The distance of the point P from the origin is
$\sqrt{{\left(2-0\right)}^2+(3-0{)}^2+(1-0{)}^2}=\sqrt{2^2+3^2+1^2}=\sqrt{4+9+1}=\sqrt{14}$
