No. Not directly. It needs to be 18 inches away... in length, not distance according to the UPC. An 18 inch water heater flex would work or 18 inches of copper tube with a pex adapter on the end will work.
To find the volume of a tube, you can use the formula for the volume of a cylinder: ( V = \pi r^2 h ). For a tube with an 18-inch diameter, the radius is 9 inches (or 0.75 feet). The height is 40 feet. Plugging in the values: ( V = \pi (0.75)^2 (40) \approx 70.69 ) cubic feet.
18 inches = 45.72 centimetres.18 inches = 45.72 centimetres.18 inches = 45.72 centimetres.18 inches = 45.72 centimetres.
18 inches / 1 yard = 18 inches/36 inches = 1/218 inches / 1 yard = 18 inches/36 inches = 1/218 inches / 1 yard = 18 inches/36 inches = 1/218 inches / 1 yard = 18 inches/36 inches = 1/2
If the perimeter is already measured in inches, there is nothing to convert. There are 18 inches in a perimeter of 18 inches.
18*18*36 = 11,664 cubic inches
18 x 18 x 36 = 11,664 cubic inches
If the diameter of a circle is 18 inches then its radius is 18/2 = 9 inches
18 inches is 1 foot 6 inches.
18 inches.
18.8 centimeters = 7.4015748 inches.
