Answer:
The diameter of the rug is [tex]4\ ft[/tex]
Step-by-step explanation:
we know that
The circumference of a circle (circular rug) is equal to
[tex]C=\pi D[/tex]
where
D is the diameter of the circle
In this problem we have
[tex]C=12.56\ ft[/tex]
substitute in the formula and solve for D
[tex]12.56=(3.14)D[/tex]
[tex]D=12.56/(3.14)=4\ ft[/tex]
