Volume of a cylinder = (pi) (radius)2 (length)Volume of the pipe section, with dimensions in feet = (pi) (1)2 (8) = 8 pi = 25.133 cubic ft (rounded)
The diameter of a log cannot be determined from its length.
The volume of a cylinder (the interior volume of the pipe) is calculated by determining the area of the cross-section and multiplying times the length. Cross-section area = pi (r2) = pi (12) square feet = approximately 3.14 square feet Volume of the pipe section = 8 x 3.14 = about 25.1 cubic feet

Incision and drainage of Skene's glands are not reported using Female Genital System, but instead reported using Surgery section, Urinary system codes.
If you have a physical cylinder to measure, measure the "width" of the circle that is the cross section of the cylinder. That is the diameter, Half the diameter is the radius.
The hydraulic diameter for any cross section is: Dh= 4 * A / Wp Where Dh = hydraulic diameter A = cross sectional area Wp = wetted perimeter
You can find information about drainage contractors through websites such as the small business section found on Yahoo!. If you have a specific business in mind you can also research them using the Better Business Bureau website.
