**A sound wave with intensity 2x10^(-3) W/m^2 is perceived to be modestly loud. Your eardrum is 6.0 mm in diameter. How much energy will be transferred to your eardrum while listening to this sound for 1.0 min?**

P=IA=(intensity)(area)

=2x10^(-3) * (pi (6x10^-3)^2)

=2.2610x10^-7 W

P=delta E/ delta t

=2.2610x10^-7 J/s * 60 s

=1.3572x10^-5 J

But this is not the right answer. I have no idea what I did wrong. Can someone please help me? Any help is greatly appreciated! Thanks!
