Sound spreads radially in all directions from a source with power 15.3 W. If the intensity you experience is 3.00×10−6 W/m2, how far away are you from the source? answer in meters?
You have shown that you are pretty good at creating different fake names. Now try dividing the total power by the sphere area at R, to get the known power per area. Then solve for R
