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.
since the volume of a right cylinder is height x area of base, the area of the base is Pi * r^2 (r is radius which is 1/2 of diameter), so the area of the base did not change, while the height is doubled so the volume is doubled.
