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 area of a sector of a circle that has a diameter of ten inches if the length of the arc is ten inches is: 25 square units.

Your question is meaningless - a diameter of 1.75 inches is 1.75 inches in length.
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.
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 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.
Approx. 25 (8 X PI)
30 inches. The diameter is twice the length of the radius.
