Assuming you are on a boat and you are using a standard sized anchor, then if the water is 20 feet deep you'd use 20 feet of line.
A general rule for anchoring is to use a scope ratio of 7:1 in calm conditions, which means for 20 feet of water depth, you should use 140 feet of anchor line. In rougher conditions, a scope of 10:1 may be more appropriate, requiring 200 feet of line. Always consider factors like wind, current, and type of seabed when determining the appropriate amount of anchor line.
The capacity of that section of line is (pi R2 L) = 333.79 cubic feet = 2,496.95 gallons. (rounded) We have no way of knowing how much water is actually in it. It may even be empty.
It is 2,178,000 cubic feet.

You need to carefully choose a spot that is protected from wind and waves. Look for a smooth and even bottom, ideally no deeper than 15 feet. To properly anchor, you must first slowly lower the anchor, bow into the wind, engine idling. When the anchor hits the bottom, but before the attached chain begins to coil up, signal the helmsman to put the engine into reverse. Lay out the chain attached to the anchor onto the bottom, and then feed out about 7:1 line, which means a 15 foot depth, plus about a 4 foot height above the water requires about 133 feet of anchor rode (as the line attached to an anchor is known). When the rode is tight, stop the engine. Then make sure you don't drift! if you dont' have a motor.....then you'll need to do the same thing into the wind, and use the backed jib or main to lay out the rode. Much more difficult.
60 feet 60 Feet for short term in calm waters. The rules, 3:1 for Short term calm conditions. 5:1 For overnight and attended in normal conditions. 7:1 for overnight, unattended and potential storm conditions example, in 20 feet using 3:1 you need 60 feet... More than 7:1 offers little increase in angle.

An old chestnut this one. Whilst in the boat, the anchor displaces its weight in water, when under the water and lying on the bottom, it only displaces its volume. As it is made from iron which is much denser than water, its volume is much less than the volume of water which equals its weight. So it will displace less water than before it is dropped.
