Its also known as stress free breathing Or technicaly known as balanced breathing
Answer:
The volume of a cylinder is expressed as:
Volume = πr²h
where r is the radius of the base and h is the height of the cylinder. If the r is doubled then,
Volume = π(2r)²h
Volume = 4πr²h
The volume is four times as much the original volume.
