Given the radius of 18 in, we can find the area and the circumference of the circle.
Explanation
[tex]\begin{gathered} Area=\pi r^2=18^2\pi\text{ }≈\text{ }1017.9 \\ Circumference=2\pi r=2\times18\pi=36\pi\text{ }≈\text{ }113.1 \end{gathered}[/tex]
Answer:
Area = 1017.9 square inches
Circumference = 113.1 inches
