The area of a circle can be calculated using this formula:
[tex]A=\pi r^2[/tex]Where "r" is the radius of the circle.
The circumference of a circle can be found using this formula:
[tex]C=2\pi r[/tex]Where "r" is the radius of the circle.
In this case you know that the area of this circle is:
[tex]A\approx167.3306in^2[/tex]Then, you can substitute this value into the first formula and solve for "r". Use:
[tex]\pi=3.14[/tex]Then:
[tex]\begin{gathered} (167.3306in^2)=(3.14)r^2 \\ \\ \frac{(167.3306in^2)}{3.14}=r^2 \\ \\ r=\sqrt[]{(\frac{167.3306in^2}{3.14})} \\ \\ r=7.3in \end{gathered}[/tex]Now you can substitute this value into the formula for calculate the circumference of a circle:
[tex]\begin{gathered} C=(2)(3.14)(7.3in) \\ \end{gathered}[/tex]Finally, evaluating, you get:
[tex]C=45.844in[/tex]The answer is:
[tex]45.844in[/tex]
