Answer:
[tex]6\pi[/tex] inches
Step-by-step explanation:
The area of a circle is [tex]\pi r^2[/tex].
Since [tex]\pi r^2=9\pi[/tex]
[tex]r^2=9[/tex]
And
[tex]r=3[/tex]
Since the radius is 3 inches,
the diameter would then be 6 inches. (3 * 2)
The circumference of a circle is [tex]\pi d[/tex], d being the diameter.
Hence, the circumference is [tex]6\pi.[/tex]
