Answer: We know that the formula for the circumference of a circle is:

Circumference = 2πr

where r is the radius of the circle.

In this problem, we are given the circumference, which is 5π ft, so we can set up an equation:

5π = 2πr

Dividing both sides by 2π, we get:

r = 5/2 feet

Now that we know the radius, we can use the formula for the area of a circle:

Area = πr^2

Substituting in the value of r that we found, we get:

Area = π(5/2)^2

Area = π(25/4)

Simplifying, we get:

Area = 25π/4

Therefore, the area of the circle is 25π/4 square feet.
