I am having some trouble trying to figure out these two problems, if someone can give me some hints as to how to answer them I would appreciate it. Thank you!! 
The bowhead whale can produce a sound that if heard at a distance of 3.00m, it would have a loudness of 130dB.
a).What is the intensity of the whales sound in W/m^2 at the distance of 3.00m?
I=P/A
b.) How far can you be away from the whale and still hear the sound? (Assume a point source and ignore reflections and absorption./0
I3m=3.00m
I=P/4(pi)r^2
