The volume of a right circular cylinder can be approximated as follows: volume = ? r2h; where r is the radius of the cylinder and h is the height of the cylinder; ? 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 7 meters
