A point source of source emits a tone with a power of 45 w

A point source of source emits a tone with a power of 45 W that has a frequency of 429 Hz. It emits this tone into air with a density of 1.21 kg/m3 and a speed of sound of 343 m/s. If an observer stands 4.7 m away from the sound, calculate the pressure amplitude in Pascals of the sound that he observes.
