I need electrical help?

Just bought a new Maytag stove. My mother is converting from gas to all electric. I took some electric cles in school but i dont remeber to much about ohms law. I need to know what size wire and what size of double breaker i will need for this stove. The stove uses 11.0 kW @ 240V / 8.3 kW @ 208V . I think i will need 8/3 with a 40 amp breaker but im checking to make sure. Thanks
