Given
Volume of baby pool = 52ft³
Required
Determine the volume of the medium pool
Volume of a cylinder is calculated as:

Hence, the volume of the baby pool is:

where r and h are the radius and height of the baby pool
Represent the height and radius of the medium pool as H and R
From the given parameters in the question
and 
and 
The volume of the medium cylinder is calculated as

Substitute 4h for H and 4r for R
