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.
We need to do two multiplications to work out the volume. We calculate the area of one face (or side) and multiply that by its height. The examples below show how there are three ways of doing this. Area = 6 x 4 = 24. Volume = Area x 2. Volume = 24 x 2 = 48 cubic units. Area = 6 x 2 = 12.
