You did not configure network on R2, so connection between R2 and R3 wil not be established.
If you want to advertise static routes into EIGRP you will have to redistribute it.
router eigrp 100
 no auto-summary

If you don't want routers to be able to establish neighbor relations on networks - - (to send hello packets) you should configure interfaces fa0/0 as passive interfaces on R3 actually is Gi0/0 interface, not fa0/0 configured with IP address
router eigrp 100
 passive-interface <type>0/0

Although technically it is not needed currently - it would be recommended to add no auto-summary command to EIGRP process on R3
