Applications of Convections
Car engines are cooled by convection currents in the water pipes. Water is a very good substance to carry the unwanted heat away from the engine to the radiator.
Applications of Radiation
We wear white or light-coloured clothes in summer because they are poor absorbers and good reflectors of heat. This way they keep us cool. On the contrary, we prefer to wear dark-coloured clothes in winters because they absorb most of the heat of sun and keep our body warm.

Answer:
A good example would be heating a tin can of water using a Bunsen burner. Initially the flame produces radiation which heats the tin can. The tin can then transfers heat to the water through conduction. The hot water then rises to the top, in the convection process.
