- R is the radius of the circle lying at the base of the cylinder;
- h - the height of the cylinder (the distance between the forming circles);
- π is a constant (π = 3.14).

For example, in the space of a given cylinder whose base is the circle of radius R. the Height of the

V = π*R2*h.

**cylinder**equal to h. Then, with these data, the volume**of the cylinder**V can be found as follows:V = π*R2*h.

From the first formula we can deduce other, because we know that the area of a circle can be found as: S = π*R2, R2 = d2/4. From this it follows:

V = S*h

V = π*(d2/4)*h, where d - diameter of the base

V = S*h

V = π*(d2/4)*h, where d - diameter of the base

**of the cylinder**circumference.
