Hi i need some help with a problem: A submarine has a 40.0cm diameter window 8.50cm thick. The window can withstand forces up to 1.10x10(adsbygoogle = window.adsbygoogle || []).push({}); ^{6}N. What is the submarine's maximum safe depth?

The pressure is maintained at 1.0atm and it's in salt water.

Salt water density = 1025 kg/m^{3}.

the equation that i used was p = p_{atmos}+ [tex]\rho[/tex]gd

p = 1.013x10^{5}+ (1.025^{3})(9.8)(d)

What i did to try to find p was p = F/A. <---- If this equation to find pressure is correct, how to I calculate the area from diameter and thickness?

Thanks.
