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.
You find the volume of a cylinder in the same way that you find the volume of a prism: it is the product of the base area times the height of the cylinder: Since the base of a cylinder is always a circle, we can substitute the formula for the area of a circle into the formula for the volume, like this:
