If you had a pipe of 2.78 inches in diameter how many inches long would the pipe have to be to hold one gallon of water. I need to to know how the equation would go about in addition to the answer.?

How about this plan: We'll explain how to solve the problem,
and then you go ahead and get the answer on your own.
The pipe is a cylinder.
The volume of the cylinder is: (pi) times (radius of the pipe)2 x (length of the pipe)
(Remember that the radius is 1/2 of the diameter.)
With that formula, you can find the volume of any length of pipe. You know the
diameter in inches, so the volume will be in cubic inches.
One gallon is exactly 231 cubic inches. Find what the length of the pipe has to be
in order to have a volume of 231 cubic inches.
Go to it ! You can do it !

How do you find the diameter and radius of a circle with a circumference of 2 inches?
Circumference = pi*diameter 2 = pi*diameter Divide both sides of the equation by pi: 2/pi = diameter diameter = 0.6366197724 inches radius is half of the diameter: radius = 0.3183098862 inches
How can you find the volume of a liquid in a 55 gallon drum in quarts from inches?
A 55 gallon drum is just a cylinder and, as such, the volume can be determined by the formula ¶r2h (Pi times radius squared times height). According to Wikipedia, standard 55 gallon drums are 22.5 inches in diameter and 33.5 inches high. http://en.wikipedia.org/wiki/55_gallon_drum The equation is thus 3.14 * 11.25^2 * 33.5. That comes out to 13313 cubic inches or 7.7 cubic feet.

Diameter is 2.5 inches what is circumference?
To get the circumference of a circle, the equation is pi * diameter. So, in this case, it is 2.5 * pi (3.14), or roughly 7.85. So, the circumference of the circle is about 7.85 inches.
