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]
