Because you are using the op-amp in a closed loop configuration, any output impedance at DC is virtually zero (see my previous answer). So, for the first circuit, when using the 741 op-amp the output impedance Zo=Zc||R.
For the input impedance, the wrong answer is Zi=2Mohm+R+Zc because the op-amp buffers the output resistor and capacitor from having any influence at the input and Zin is what the data sheet says about the 741 (typically 2 Mohm).
For your 2nd circuit, the output impedance is virtually zero ohms at DC for the reasons given in my previous answer. As frequency rises the output impedance rises.
