this has to be explained also and we cannot enter the area and it is a big one and we need all the measurments

Assuming the shape of the tank is some simple geometric figure that you can use a formula for the volume:
STEP #1
To find the dimensions of the tank you must first calculate how far the tank is from a specific point. One easy way to do this is walk a distance from the tank untill it is the same visual width as a specific measurement held from your eyes a certain distance (for example when the tank appears the same width as 3 inches held 3 feet from the eyes.) now mark this spot on the ground. Then walk to another point (sideways) to another point that also is a distance away such that it appears the same width as before. Mark this point. These 2 point lay on a circle with the center of the tank at its center, this also means that the 2 points plus the point at the center form an isocoles triangle. Stand at either point and measure the angle between the center of the tank and the other point. Record this angle. Measure the distances between the 2 points. You know have 2 angles (other angle is the same as the one measured, since it is an isocoles triagle) and 1 side. The distance of either point from the center of the tank is 2 x cos (angle measured) x (distance between points).
STEP #2
Now you know how far away it is from your marked points. Next , while standing at one of the marked points, simply hold a ruler a fixed distance from your eyes and measure the dimensions as they appear on the ruler. The actual distances will be given by: dividing the width on the ruler by the distance your eyes are from the ruler, then multiply by the distance from the tank calculated in the first step.
STEP#3
Now you know the dimensions of the tank, use whatever geometric formula for volume depending on the tanks shape.

You'll have to use geometry. You didn't explain the basic shape of the propane tank, so I'll assume it's the standard tank you see in people's yards in the country -- a long tube sitting on it's side with rounded ends.
There are several things you need to know to determine the size of the tank. First, you need the tank's diameter, it's length, and just how rounded the ends are. Once you have these three pieces of information, you can use standard geometry formulae for the volume.
Volume of a cylinder: length * pi * radius * radius.
Volume of a circle: 4/3 * pi * radius ^ 3
If you can stand a known distance from the tank, you can use simple geometry to determine the diameter and length. If you draw a picture with a "top view" of the situation, it will make sense.
Draw the tank. Then add a dot that represents you a little away from the tank. Two dashed lines from you to each end of the tank.
What you have now is a triangle. By measuring the angle between the lines (which you have to do in person, not on the paper), and knowing the distance to the tank, you can determine the length of the tank.
Repeat in a similar fashion going from top of tank to bottom of tank to determine the diameter.
Good luck.

It will be difficult without entering the yard, but possible if you have the right equipment and the time.
You would need to set up a base line and measure the angle of different points on the tank. The base line would need to be vertical for vertical dimensions and horizontal for horizontal dimensions.
Once you have the baseline and the angles, you can use the laws of sines and cosines to determine the tank’s measurements. With that, the volume can be calculated.

No dog should ever be allowed to roam free. All dogs should be contained on a leash, in a fenced area, or at least very closely supervised by a capable adult. Dogs allowed to roam are a danger to themselves, to other pets, and to people. My greyhound was nearly killed by a dog that was allowed complete autonomy, he is a big friendly great dane but on that day he savagely attacked my dog (who was on a leash on my property). I have a greyhound without a fenced in yard, no problem. We just make sure to walk him several times a day, always on a leash. We also spend an hour, a few days a week, at the dog park. It's up to you if you want to make that much of a commitment, a fence would be much easier. 3 acres is a lot more than most dogs ever have. Our dog park isn't even 3 acres. I hope you enjoy your pet.

measure the length of fenced it takes up and how high up the fence it goes and then find the thickness of the walls of a propane tank the find the volume of a cylinder and a sphere that fits your measurements.

You could take a picture of the tank, and have something of a known length to compare with, and measure the known, and do a linear extrapolation.
Commercial tanks come in a few standard sizes. Once you know its capacity you could find a tank vendor, and get the exact dimensions from them.

Get a pair of binoculars. Peek over fence. Read label on tank.

Use some binoculars and get the name brand. Look it up on the manufacturers site. Yay!
Or maybe you could build a replica and then use ratio's to find the real dimensions.

Estimate the diameter and the height, then go to

and do the math on the cylinder volume.
