Answer
The circumference of the circle is$\text{18}\pi \text{ m or 56}\text{.6 m}$and the area of the circle is\[81\pi \text{ }{{\text{m}}^{2}}\text{ or 254}\text{.6 }{{\text{m}}^{2}}\].
Work Step by Step
A circle is a round plane figure whose boundary consisting of points equidistant from a fixed point (center). The area is expressed as the space enclosed between closed figures to the extent of a two-dimensional figure.
Use the formula to compute the circumference of a circle can be shown below,
$\begin{align}
& \text{Circumference of circle}=\text{2}\pi r \\
& =\text{2}\times \pi \times 9\text{ m} \\
& =\text{18}\pi \text{ m}
\end{align}$
Or, Circumference of circle $\approx 56.6\text{ m}$
Compute the area of the circle as mentioned below,
\[\begin{align}
& \text{Area of circle}=\pi {{r}^{2}} \\
& =\pi \times 9\text{ m}\times 9\text{ m} \\
& =81\pi \text{ }{{\text{m}}^{2}}
\end{align}\]
Or, Area of circle \[\approx \text{254}\text{.6 }{{\text{m}}^{2}}\]
Hence, the circumference of the circle is$\text{18}\pi \text{ m or 56}\text{.6 m}$and the area of the circle is \[81\pi \text{ }{{\text{m}}^{2}}\text{ or 254}\text{.6 }{{\text{m}}^{2}}\].
