Calculating Tank Volume from Liquid Depth: A Practical Guide

AI Thread Summary
To calculate the volume of liquid in underground cylindrical storage tanks based on the depth of the liquid, the formula for the volume of a cylinder can be applied. Given the tank's diameter of 1.2 meters, the radius is 0.6 meters. The volume can be calculated using the formula V = πr²h, where h is the height of the liquid measured in meters. For liquid depths ranging from 6 to 30 cm, converting these measurements to meters will yield volumes between approximately 1000 to 2000 liters. This practical application is essential for proper disposal and management of the stored petrol.

Hi guys/gals,

I have a problem, my maths isn't that great. I have some underground storage tanks with petrol in them. and I can only measure depth of the liquid at the bottom. however i want to know the volume for disposal purposes. Can anyone tell me how to find the volume given the height of the petrol from the bottom? details are the tanks are 1.2m diameter, and the height of the liquid from the bottom of the tanks range between 6 to 30cm. the volumes of the tanks are estimated to be about 1000 to 2000 litres. This is a real life application, not homework.
the tanks are laying in the ground like a big pipe, not standing upright like a watertank.

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Six Pencil Puzzle'

Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
