Answer:  2

Step-by-step explanation:

The circumference of a circle is 2*radius*pi.

We can set up an equation as we know the circumference as 4pi.

4pi = 2*radius*pi

Divide both sides by pi:

4 = 2*radius

Divide both sides by 2:

radius = 2

Answer:

2 ft

Step-by-step explanation:

The equation for circumference is:

[tex]C=2\pi r[/tex]

We can plug in the given value for circumference to solve for the radius.

[tex]4\pi=2\pi r[/tex]

Divide both sides by 2π

[tex]\frac{4\pi}{2\pi}=r\\r=2\ ft[/tex]
