Step-by-step explanation:
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
Open bracket
Collect like terms
Recall that
So, the expression becomes
Hence, the medium pool can hold 
of water
Option: step 2.
Because the student divided only the right side by 2. If you divide one side by a number you have to do the same with the other side to maintain the equality.
