A. Here we assume a sound from a HEMISPHERICAL speaker has a level of $131\mathrm{.}11$dB at a 

distance of R from a speaker at The Gorge Amphitheater. Calculate the intensity of the sound.

B$)$ Find the intensity of the sound at $85\mathrm{.}00$dB and then find the factor by which this distance is greater than R$.$
