NL2 6m: KK, RR pot, A flops, should I c-bet?

[Caelallaiach]

Only 30 hands so far, but I include stats for completeness:-

Hero is 18/13/3.0 over 30 hands.
Villain is 27/21/2.0 over 30 hands.

Sorry if this is a stupid question, but is it standard to bet here? If so, how much?

About $0.50 the right bet size?
