What is the distance around the outside of the circle of water in terms of pi?
First off, what you appear to be asking for is the circumference, the length of area around a circle(or in this case, a body of water). To find the circumference, measure for the diameter, the diameter is the length of one side of a circle to another, this distance must go through the center of the circle. All you have to do is multyply the Diameter by pi.
How many liters of water are in a 24 foot round pool that is 4.5 feet deep?
If the 24' is the circumference (distance around the outside), then: Diameter = Circumference / pi = 7.6394 ft.Radius = Diameter / 2 = 3.8197 ft.Area = pi * radius^2 = 45.8366 sq. ft.Volume = A * depth = 206.2648 cu. ft. = 5841.42 liters (because 1 cubic ft = 28.32 liters). If the 24' is the diameter, then your numbers are: Radius = 12'Area = 452.39 sq. ft.Volume = 2035.75 cu. ft. or 57652.5 liters.
How do you find the diameter of water?
Only circles (or spheres) have a diameter
How much water does a 10' by 10 piece of pipe hold?
The measurement units for the second 10 are not given. Furthermore, it is not clear whether that measure refers to the radius, diameter or even circumference of the pipe. Consequently, it is not possible to answer the question.
How many gallons of water will it tale to fill a cylinder 78 inches by 18 feet?
It is not possible to answer the question because you have not stated which of the two given measures is the height and whether the other measure is the radius or diameter or circumference. Without these critical items of information it is impossible to give a sensible answer.
