1. The problem statement, all variables and given/known data
A sound wave radiates from a source to all directions, if the power of the sound is 200 watts then the intensity of the sound wave 100m from the source is what?

2. Relevant equations
is this question complete / incomplet? is it missing any information that I need to solve the problem. what equation do i use?

3. The attempt at a solution

i tried B (200)log of 10 =(100m)log I/Io ???

Imagine a sphere of radius 100m, how big is its area? How is power related to intensity?
