Question

A source emits sound uniformly in all directions. There are no reflections of the sound. At a distance of 12 m from the source, the intensity of the sound is 1.7 × 10-3 W/m2. What is the total sound power P emitted by the source?

Would I do 1.7e^-3 (12) ?

Sound is reduced by distance squared.

I= 4PI(12)^2*1.7E-3 watts
