Similarities are that these figures have curved surfaces, not flat faces. A cylinder is similar to a prism, but its two bases are circles, not polygons. Also, the sides of a cylinder are curved, not flat. A cone has one circular base and a vertex that is not on the base.
Differences:
A cone is a 3-dimensional solid object that has a circular base and a single vertex. ... Cylinder : A cylinder is a 3-dimensional solid object that has two parallel circular base connected by a curved surface.
