Answer:

[tex]15.7\ ft[/tex]

Step-by-step explanation:

we know that

The circumference of a circle (the length of the piece of ribbon) is equal to

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

we have

[tex]r=2.5\ ft[/tex]

substitute the value

[tex]C=2\pi (2.5)=5 \pi\ ft[/tex]

assume

[tex]\pi=3.14[/tex]

[tex]5 \pi=5*3.14=15.7\ ft[/tex]
