Need some assistance on what I am missing(adsbygoogle = window.adsbygoogle || []).push({});

"A tank contains mercury, whose density is 13 600 kg/m3. Find the force exerted by the mercury on a circular plug at the bottom of the tank. The plug has a diameter of 2.54 cm, and is located 37.6 cm below the surface of the mercury". The answer is 25.4 N

1) I have tried p=F/A ending with A*p=F or 2.54*136000=F (Wrong)

2) and F=phgA and again the number to big

3) Finally I tried P2=P1+pgh with P1=(1.01x10^-5) again too large of an answer

Am I missing something from try #1?

Thanks for any assistance
