Cylinder. A cylinder has two flat ends in the shape of circles. These two faces are connected by a curved face that looks like a tube. If you make a flat net for a cylinder, it looks like a rectangle with a circle attached at each end.
The bases are usually circular in shape. The perpendicular distance between the bases is denoted as the height “h” of the cylinder and “r” is the radius of the cylinder.
Having radius r and altitude (height) h, the surface area of a right circular cylinder, oriented so that its axis is vertical, consists of three parts: the area of the top base: πr. the area of the bottom base: πr. the area of the side: 2πrh.
Total area of a cylinder A=2πrh+2πr²
The formula for the volume of a cylinder is V=πr²h
