I'm not really sure what this is even asking.

- math -
**Reiny**, Monday, April 25, 2011 at 8:21amI made a diagram according to you description and concluded the following

Since each of the 4 "verticals" is 12 inches, that would leave 5 feet or 60 inches for the circle and the square base

Let the radius of the circle be x feet

then the length for the base would be 5 - 2πx feet

and each side is 5/4 - (1/2)πx

let the total area of top and bottom be A

A = πx^2 + (5/4 - (1/2)πx)^2

differentiate, set that equal to zero and solve for x

I will let you finish the messy part.
