Answer:
6.28 feet
Step-by-step explanation:
1.) Find the radius.
The area is given, and the formula for area of a circle is A = [tex]\pi r^{2}[/tex] Let's substitute.
3.14 = [tex]\pi r^{2}[/tex]
Divide by pi on both sides
1 = [tex]r^{2}[/tex]
Find the square root of r
1 = r
The radius is 1.
2.) Find the circumference.
C = [tex]2\pi r[/tex]
C = [tex]2\pi (1)[/tex]
Multiply 2 and 1
C = [tex]2\pi[/tex]
C ≈ 6.28
The circumference is approximately 6.28 feet.
