Question

Perpendicular distance of the point (3, 4, 5) from the y-axis, is

• A. $\sqrt{34}$
• B. $\sqrt{41}$
• C. 4
• D. 5

Answer 1

The correct option is A $\sqrt{34}$

Perpendicular distance of (x,y,z) from y axis is given by $=\sqrt{x^2+z^2}$.
=> Required distance $=\sqrt{3^2+5^2}=\sqrt{34}$.
