What is the radius of the base of the cylinder?

1) A cylinder is a geometric shape obtained by rotating a rectangle around one of its sides. Each cylinder has 2 identical bases (top and bottom) and a side surface. Any cylinder is characterized by a height h (center line) and a radius r. AND The height of the cylinder (centerline) is the perpendicular drawn from the top base to the bottom. The radius of a cylinder is the radius of its base.
2) The area of the base of the cylinder can be calculated by its radius R: Sbase. = Pi * R ^ 2.
Let’s express R. We get: R = √ (Sosn. / Pi).
