Whole rest for time signature 3/4

[Disc Magnet]

How to properly print a whole rest for a staff with time signature as:
\time 3/4?

If I try r1, the rest occupies 4 beats. So it consumes 1 bar (3 beats)
and a 1/3rd (1 beat) of the next bar as well. As I understand it, a
whole rest should occupy 1 bar only irrespective of the time
signature.

If I try r2. I see a dotted half rest. However, I want the whole rest
symbol. Please help me with this
