Answer:
The circumference is 59.66 cm
Step-by-step explanation:
we know that
The circumference of a circle (ring) is given by the formula
[tex]C=2\pi r[/tex]
If the radius is
[tex]r=9.5\ cm[/tex]
substitute in the formula
[tex]C=2\pi (9.5)[/tex]
[tex]C=19\pi\ cm[/tex] ----> exact value
assume
[tex]\pi =3.14[/tex]
substitute
[tex]C=19(3.14)=59.66\ cm[/tex]
