  • 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 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 of the cylinder circumference.
