# How can the liquid amount in gallons and liters of a cylinder be determined?

The volume of a cylinder is Pi * radius^2 * height. 1 Gallon = 3.7854 Liters. 1 Liter is 1000 cm^3. So get the radius and height in cm, then use the formula to get the volume in cm^3, then convert to gallons or liters.

### What should be used to measure liquid volumes?

The normal method of measuring the volume of a liquid is with a graduated cylinder. If you pour the liquid into a graduated cylinder, you can then read the volume off of the markings (or graduations) on the cylinder. If the amount of liquid is extremely large (let's say, a thousand gallons) then you need a different technique. Perhaps a graduated swimming pool.

### What is the measure unit of volume?

You just put a units after the volume that you found. Also, weight(lbs, oz, ect.) count as value and so to liquid measurements(gal, pint, ect.) When you are doing weight or liquid measurements, just use the unit. For example, if you find the amount of liquid inside a cylinder, and the answer is 90 gallons, you just use gallons, nothing else

### Would it be more accurate to measure the amount of water that a container can hold by using one measurement with a large graduated cylinder or two measurements with a smaller graduated cylinder?

If you measure properly, the amount of water does not change. Measurement with whatever graduated cylinder you choose will not alter the amount of liquid measured. Most people choose to measure once with a larger one, but if the amount of liquid falls between the measurement lines, you can measure the "leftover" with a smaller cylinder and find the exact answer.

### If a cylinder of radius 2cm and height 4cm is submerged in a graduated cylinder of radius 3 cm containing a liquid By how much does the liquid rise?

I would say that the liquid rises by 1.77cm... This can be obtained as follows given that cylinder of radius(r)=2cm, height(h)=4cm is submerged in another cylinder, determining the volume of the cylinder being submerged =16*pi. When this cylinder is placed in another cylinder the liquid will rise by an amount which equals the volume of the cylinder being inserted.(By Archimedes principle). Using this 16*pi, determine the height using radius= 3cm , we get h=1.77cm

### Whether an object that sinks or floats in a fluid is determined by?

Sinking or floating is determined by the density of the liquid and the density of the object. Density is mass/volume. When you place an object in a liquid, a certain amount of volume is displaced by the object. If that object puts more mass into the volume displaced than what the original mass was of the liquid in that volume was, then the object will sink. Therefore an object that is more dense than a…

### What is the formula for calculating gallons of liquid in a cylinder?

To calculate the volume of a cylinder, use the following formula: pi multiplied by the cylider's radius squared multiplied by the cylinder's height. Converting to gallons: Convert cubic feet to gallons by multplying by 7.48051945. Convert cubic inches to gallons by multiplying by 0.00432900431 Note: All of the cylinder's dimensions must be in the same unit of measurement in order to proceed! For instance, if the cylinder's height is measured in inches, its radius must…

### What are the steps for the use of a graduated cylinder?

First, to insure greatest accuracy, one should make sure conditions are appropriate for the use of the cylinder, meaning that most graduated cylinders are calibrated for use with water at 20 degrees Celsius. One can determine this by looking for "20° TC" or "20° TD" marked on the cylinder. "TC", or "to contain", means that the volume of liquid contained in the cylinder is what is indicated by the graduated markings. "TD", or "to deliver"…

### Can you use a graduated cylinder to measure the volume of a regular shaped object?

Yes you can. You put liquid (usually water) in the graduated cylinder. Then record how much liquid you put in it. Next, put the object in the graduated cylinder. Look at where the water level is now. Take that number and subtract the amount of water you put in and that should give you the approximate volume of the object.
