The answer depends on what the formula is for: surface area, volume, mass, density, etc. And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.
Furthermore, there is not enough information in the question to give an answer in any of these cases.

Pi * r-squared * hAnswerAnd if your cylinder is not a right circular one, things get a bit tricky from there. =)
A (right circular) cylinder has 2 circular faces... one on top, and the other the bottom.
volume of a right circular cylinder is v = (pi)(h)(r^2) if you want the answer in cubic meters the height and the radius must be in meters.
The volume of a right circular cylinder with a diameter of 6.8 in and a height of 2 feet is: 871.6 cubic inches.
V=hπr2
Archimedes
pi * radius2 * height
rc = d/2Radius equals diameter divided by 2.In a right circular cylinder there are 2 circles - one of the base and one on the top of the cylinder. If we are going to get the radius of one of them, it will be equal to one-half the measure of the diameter of the whole circle, or r = d/2.
Volume of the cylinder: pi*radius*radius*height
Pi x r² x h
Pi x r² x h

Strictly, if it has a circular base, it is a circular cylinder. Otherwise, it could have an oval base. If the long axis is at right angles (perpendicular) to the plane of the base, then it is a right circular cylinder.
It is 10 cm.
