Answer

Final Answer: The radius of the foundation is \(\boxed{48}\) ft.

Steps

Step 1 :The problem provides that the circumference of the foundation is 4 times the radius, increased by 109.44 ft. This can be represented by the equation \(2\pi r = 4r + 109.44\), where \(C = 2\pi r\) is the formula for the circumference of a circle and \(r\) is the radius.

Step 2 :Solving this equation for \(r\) will give us the radius of the foundation.

Step 3 :By simplifying the equation, we find that the radius \(r\) is approximately 48 ft.

Step 4 :Final Answer: The radius of the foundation is \(\boxed{48}\) ft.
