Using 55.8 pb-1 of e+e- collisions recorded at the ψ(3770) resonance with the CLEO-c detector at CESR, we determine absolute hadronic branching fractions of charged and neutral D mesons using a double tag technique. Among measurements for three D0 and six D+ modes, we obtain reference branching fractions B(D0→K-π+)=(3.91±0.08±0.09)% and B(D+→K-π+π+)=(9.5±0.2±0.3)%, where the uncertainties are statistical and systematic, respectively. Final state radiation is included in these branching fractions by allowing for additional, unobserved, photons in the final state. Using a determination of the integrated luminosity, we also extract the cross sections σ(e+e-→D0D̅ 0)=(3.60±0.07-0.05+0.07) nb and σ(e+e-→D+D-)=(2.79±0.07-0.04+0.10) nb.
