The volume of a right circular cylinder can be approximated as follows:

Volume = πr2h;
where r is the radius of the cylinder and h is the height of the cylinder;
π is a constant that is roughly equal to 3.

Using the simple approximation above, calculate the volume of a right circular cylinder with a radius of 2 meters and a height of 9 meters.
