a) Calculate the pressure at an ocean depth of 550 m. Assume that the density of sea water is 1022 kg/m3 and that the air above exerts a pressure of 101.3 kPa.(adsbygoogle = window.adsbygoogle || []).push({});

b) At this depth, what force must the frame around a circular submarine porthole having a diameter of 32.0 cm exert to counterbalance the force exerted by the water?

I found the answer for (a) to be 5609880 Pa, but I am stuck on part (b).
