Its not clear from the question what formulas are being requested, but:
Surface area of a right cone (one where a line from the tip through the center of the base is perpendicular to the base)
A = πr2 + π r(r2 + h2)½
Volume of a right cone
V = (1/3)πr2h
Surface area of a cylinder
A = 2πr2 + 2πrh
Volume of a cylinder
V = πr2h
where
π is the number pi
r is the radius of the figure
h is the height of the figure perpendicular to the base.
The equations for a slanted cone are more complex - so ask again with that specification if that is what you are looking for.

The volume of a cone is one third the volume of a cylinder of the same height. The volume of a cylinder is πr2h, so the volume of a cone is 1/3πr2h.
Since the base of a cone is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder. So, the formula for the lateral surface area of a right cone is L. S. A. = πrl, where l is the slant height of the cone.
cylinder has 2 and cone one
A cylinder has 3 faces, a cone 2. A cylinder has 2 edges, a cone 1. A cylinder consists of 2 circles and 1 rectangle, a cone consists of 1 circle and 1 semicircle.
No, there is no reason for a cone and a cylinder to have anything congruent.
