Find Out Things About Cylinder

Notes about cylinders:

• The radius R, or the distance from the center of a cylinder to its edge, and its length, L are usually the defining property of a cylinder. If your cylinder is standing upright, you might call the "length" a "height" instead.
• The diameter, or the distance across a cylinder that passes through the center of the cylinder is 2R (twice the radius).
• The surface area of an open ended cylinder (as shown) is 2RL
• If the cylinder has caps on the ends, the surface area is 2RL+2R²
• The volume of a cylinder is R²L
