The most apparent signs and symptoms of a carotid artery blockage include a transient ischemic attack, bruit and a stroke, according to the National Heart, Lung, and Blood Institute.
Measure the length of the cylinder with a measuring tape. Multiply this measurement by the result obtained in the above step. (Example: if the length of your cylinder is 24 inches, then 24 x 113.04 = 2712.96 square inches) Divide the square inch volume of the cylinder by 1728 to get the cubic feet of the cylinder.
If the cylinder has a radius r and length (height) h, then its volume is given by. Having a right circular cylinder with a height h units and a base of radius r units with the coordinate axes chosen so that the origin is at the center of one base and the height is measured along the positive x-axis.
