Circumference of a circle:
[tex]C=2\cdot\pi\cdot r[/tex]Area of a circle:
[tex]A=\pi\cdot r^2[/tex]For the given circle:
[tex]\begin{gathered} r=9ft \\ \\ C=2\cdot3.14\cdot9ft \\ C=56.52ft \\ \\ A=3.14\cdot(9ft)^2 \\ A=3.14(81ft^2) \\ A=254.34ft^2 \end{gathered}[/tex]Then, the circumference is 56.52 feet and the area is 254.34 square feet
