Final answer:
The circumference of the circle is 8π ft.
Step-by-step explanation:
The circumference of a circle can be found using the formula:
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, the radius is given as 4 ft. So we can substitute the value of the radius into the formula:
C = 2π(4 ft)
Since we want the answer in terms of π, we can leave it in that form.
The circumference of the circle is 8π ft.
