Answer:
[tex]6.5\pi\ in[/tex]
Step-by-step explanation:
we know that
The circumference of a circle is equal to
[tex]C=2\pi r[/tex]
we have
[tex]r=3\frac{1}{4}\ in[/tex]
Convert to an improper fraction
[tex]r=3\frac{1}{4}=\frac{3*4+1}{4}=\frac{13}{4}\ in[/tex]
substitute
[tex]C=2\pi(\frac{13}{4})[/tex]
[tex]C=\frac{13}{2}\pi=6.5\pi\ in[/tex]
