Sound Power Emitted Calculator

I want to calculate
Sound Wave Intensity(I) = W/m2
Radius or Distance from Point Source(r) = m
Power Emitted(PAV) = W
 

Sound Power Emitted formula

Power Emitted: PAV=I*4PI*r2

where PAV = Power Emitted, r = Radius or Distance from Point Source, I = Sound Wave Intensity.

When Sound Wave Intensity(I) = 20W/m2, Radius or Distance from Point Source(r) = 2 m, Then Power Emitted = 1004.8 W.
