Question

Distance of the point $(3,4,5)$ from the origin $(0,0,0)$ is

• A. $\sqrt{50}$ units
• B. $3$ units
• C. $4$ units
• D. $5$ units

Answer 1

Answer: (A)

Distance between the points $(3,4,5)$ and $(0,0,0)$
$=\sqrt{{\left(3-0\right)}^2+{\left(4-0\right)}^2+{\left(5-0\right)}^2}$
$=\sqrt{9+16+25}$
$=\sqrt{50}=5\sqrt{2}$ units
