(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A concert loudspeaker suspended high off the ground emits 27.0 W of sound power. A small microphone with a 0.700cm^2 area is 55.0 m from the speaker.

What is the sound intensity at the position of the microphone?

How much sound energy impinges on the microphone each second?

2. Relevant equations

I = P/a

I1 /I2 =R2^2 / R1^2

3. The attempt at a solution

I tried this as the solution

27W / (pi * (55m^2)) = .00284W/m^2. The answer is incorrect.

I could not answer question 2 since it is realted to question 1. PLEASE HELP
