Answer:
[tex]\text{Circumference of circle}=6\pi\approx 18.85[/tex]
Step-by-step explanation:
We are asked to find the circumference of circle with radius 3 ft.
[tex]\text{Circumference of circle}=2\pi r[/tex]
Upon substituting [tex]r=3[/tex] in above formula we will get,
[tex]\text{Circumference of circle}=2\pi\times 3[/tex]
[tex]\text{Circumference of circle}=6\pi\approx 18.85[/tex]
Therefore, the circumference of circle is 6 pi feet or approximately 18.85 feet.
