A probe is placed at the very bottom of a cylindrical silo to measure the material properties in order to ensure proper storage conditions of a proprietary liquid before processing. If the silo is 115 feet tall and 22 feet in diameter and is filled to 80% if its total height, what is the hydrostatic pressure felt by the probe in units of atmospheres

Answer is in the photo. I couldn't attach it here, but uploaded it to a file hosting. link below! Good Luck!

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
