The radius on the plan is 6 feet, hence the diameter will be
diameter on plan = 6*2 = 12 feet
Given Data
First pool
Radius of pool on Plan/Blue Print = 5 inches
actual Radius = 20 feet
Second pool
Radius of pool on Plan/Blue Print = ???
actual Radius = 24 feet
From the first pool, we can see that the Proposed Radius is 4 time the Planned radius
Hence, for the second pool let us apply similar logic
Actual radius = 4*x
24 = 4x
divide both sides by 4
x = 24/4
x = 6 feet
Diameter = 6*2 = 12 feet
