Auch in diesem instructable, ich so finden Sie die Lautst�rke der eine Kugel lernen Sie. Aber Erstens, die Grundlagen.
Eh bien, dans cette instructable, je vous enseigne comment trouver le volume d'une sph�re. Mais en premier, les notions de base.
Step 1: What the Gitmo Is a Sphere, Anyway?
Well, just to be simple, it is just a figure with no edged or corners, and the distance from the midpoint of the sphere to any place on the surface of the sphere is the exact same. Yes, this might seem like useless information at first, but you will need this knowledge later on.
Step 2: Finally...the Formula!
Step 3: The Equation...Backward?
Step 4: Now..Time for Some Problems!
Problem 2: When the volume of a circle sphere is 32/3 pi?
Problem 3: If the radius of a given sphere is 5, what is the half the volume?
1. 32/3 pi. For this problem, you need to include the cm3, because your answer would be wrong without it. Remember, radius cubed is the number and the sign after it(if there is one).
3. 250/3 pi.
Step 5: Well, What Else?
2. Lower your sphere slowly into the water. If your sphere is less dense than water, tie it with a thin thread to a small heavy object such as a lump of plasticine or a standard weight.
3. Take the new reading of the volume. This is the volume of the water + volume of sphere (+ volume of heavy object used to sink sphere).
4. If you tied your sphere to a heavy object, untie it, and lower just the object back into the water. Take the new reading of the volume of water + volume of heavy object.
5. Subtract either (volume of water + object + heavy weight) - (volume of water + heavy weight) OR (volume of water + object) - (volume of water). This answer is the volume of your sphere (or any object, really).
P.S. Make sure you know the volume of the cylinder beforehand; else, you might find yourself stranded! To find the volume of a cylinder, go here. Be sure to use a precise measuring cylinder, or you might get the calculations wrong!
Step 6: Another Option?
1. Fill a graduated cylinder to the top, making sure there is no water pushing up onto the water tension. Make the calculation of the total volume, and make sure you have another water cylinder. You can also have a pitcher with a spout sticking out of a side, and having another tray or pitcher ready to hold the extruded fluid.
2. Place the object gently into the pitcher, and watch the water rise. it will rise above the peak, and then the surface tension will break when the water pours out. then, after you are sure that the water is done flowing, separate the two, and find the volume of water in the cylinder or pitcher which the water was displaced into.
3. Voila! You have your volume.
