The depth of the ocean can be measured using principles such as sonar wherein a wave with a known speed is projected towards the bottom surface and the time lapsed until the wave returns is divided by two and them multiplied by the speed of the wave in order to calculate the distance traveled in one direction.

The diameter of the earth can be calculated numerous ways, one of which is to measure the change in angle of the earth between two points (e.g. the change in apparent height of a ship at sea level as the distance from the observer increases) and then extrapolate the total circumference of the earth, diameter can then be solved for by dividing the circumference by Pi.

What is depth as it is relating to the ocean?

Depth is a measure of distance between the surface and the ocean floor.


Do miles measure area?

Only if they are SQUARE miles; otherwise, they measure length (distance), height or depth.


Is diameter the depth?

The term diameter, relative to a circle, is the width. For a sphere, such as a planet, the distance from the surface to the center is actually the radius, which is one-half of the diameter.For a cylinder, it depends on the orientation. If you have a can and it is right-side up, then the diameter is not the depth -- it's just the distance from one side of the top "circle" to the other, passing through the center. If you put the can on its side, then the diameter could become the "depth." But this terminology is normally not used for curved geometric solids.


How do you find the cubic feet of dryer?

For the exterior you measure the lenght, width and height - in feet - and multiply them together. To measure the interior volume you will need to measure the diameter of the drum and its depth, in feet. Then volume = 1/4*pi*diameter2*depth.


What is spatial depth?

it goes in both direction to measure the distance of something from top to bottom.


What type of energy is used to measure water depth today?

The question is flawed. Water depth is a measurement of distance not energy. Unless of course you are asking about the method in which they measure water depth in which the question still makes little sense.


What are the dimensions of the Dakota Unisex pocket watch, in depth and diameter?

How do you determine the diameter of a rifle barrel?

You would measure the inside of the barrel from land to land (In other words, you would not include the depth of the rifling)


Does wavelength measure depth distance energy speed volume or time?

Wavelength is a measure of depth/distance - namely the distance between peaks or troughs in a wave. For light this is referring to peaks/troughs of signal strength. Because the front velocity of a photon of light is always constant (ALWAYS, WITH RESPECT TO ALL FRAMES OF REFERENCE IN THE UNIVERSE, NO EXCEPTIONS), the wavelength of a photon is also a direct measure of it's energy.


What is the volume in liters of a cylinder with a diameter of 2000mm and a depth of 100mm?

The volume in liters of a cylinder with a diameter of 2000mm and a depth of 100mm is: 314 liters.


What unit of measurement can you use to measure a wading pool?

You first need to decide what you want to measure about it: its length, its volume, its viscosity, etc.


Why o Can a clinometer be used to measure the depth of something?

No, a clinometer is not used to measure the depth of something. It is used to measure the angles of incline, slope, and elevation but not the actual depth.
