Answer:

5.23 yards

Step-by-step explanation:

The circumference of a circle is equal to

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

we have

[tex]r=2.5 ft[/tex]

substitute the value

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

assume

[tex]\pi =3.14[/tex]

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

convert feet to yards to get your answer:

5.23 yards
