Indented Cylinder

A cylinder is a three-dimensional shape consisting of two parallel circular bases, joined by a curved surface. The center of the circular bases overlaps each other to form a right cylinder.A cylinder is a three-dimensional shape in geometry. A cylinder is round and has a top and bottom in the shape of a circle. The top and bottom are flat and always the same size A cylinder has one curved surface and two flat faces which are identical. The two circular bases are congruent to each other. Its size depends on the radius of the base and the height of the curved surface. Unlike a cone, cube, or cuboid, a cylinder does not have any vertex.Their shapes can be classified into four types; these are right circular cylinder, elliptical cylinder, oblique cylinder, and hollow cylindrical structures. Two bases of a cylindrical structure are parallel to each other and the difference between the two bases is known as altitude or height
