The perpendicular distance of the origin from the plane $2 x+y-2 z-18=0$ is
- A18 units
- B9 units
- Correct answerC6 units
- D4 units
Solution
$\begin{aligned} \text { Required distance } & =\left|\frac{2(0)+(0)-2(0)-18}{\sqrt{4+1+4}}\right| \\ & =6 \text { units }\end{aligned}$
Hence, the correct answer is option: 'C'.
