Assuming that you are asking about the 1 inch diameter pipe that you would find at the hardware store, the average inside diameter of Sch 40 is 1.029". The formula for volume of a cylinder is pi times radius squared times height.
Pi = 3.14,
the radius would be half the diameter (1.029/2) = .5145
the height is 12 inches
3.14 x .2647 x 12 = 9.974 cu inches
The volume of a pipe that measures 8 feet in length and 24 inches in diameter is: 25.133 cubic feet (about 188 US gallons).
244.78 gallons
The length of a box that measures 18 cm is approximately 7.1 inches.
You cannot. All that can be said is that the diameter is at least 6 inches in length.
The answer will depend on which of the two measures is the length and what the other one is: radius or diameter.The answer will depend on which of the two measures is the length and what the other one is: radius or diameter.The answer will depend on which of the two measures is the length and what the other one is: radius or diameter.The answer will depend on which of the two measures is the length and what the other one is: radius or diameter.

56548.8 cubic inches = pi (3.1416) times the radius squared times the height
I get 9
Completely filled, (pi x radius squared x length in inches)/231 cu in per gallon = gallons = 13.06122449, if the inside diameter of the pipe is 2 inches. =========== Of course that assumes that the inside diameter is exactly 2 inches. For real pipes, the actual inside diameter of a pipe depends on the "schedule" of the pipe. For a "nominal" pipe diameter of 2 inches, the outside diameter will be 2.375 inches and the wall thickness could vary from .065 inches (schedule 5) to .343 inches (schedule 160) meaning that the actual inside diameter could vary from 2.245 inches to 1.689 inches.
Your question is meaningless - a diameter of 1.75 inches is 1.75 inches in length.
The length of a box that measures 18 cm is approximately 7.1 inches.
Twelve inches is a length. It can be a diameter, but if it is a diameter, you would simply say 'The circle is 12 inches diameter'. So; how big is it - it is 12 inches.
You cannot. All that can be said is that the diameter is at least 6 inches in length.
The area of the sector of a circle which has a diameter of 10 inches if the length of the arc is 10 inches is: 25 square inches.
They are measures of length.
