Answer
The fencing required to enclose the circular garden of radius\[20\text{m}\] is\[125.7\text{m}\].
Work Step by Step
For the computation of the length of fencing required, we need to find the circumference of the circular region. Compute the circumference of the region as follows:
\[\begin{align}
& C=2\pi r \\
& =40\pi \text{ m} \\
& \approx 125.7\text{ m}
\end{align}\]
Hence, the fencing required to enclose the circular garden of radius\[20\text{m}\] is\[125.7\text{m}\].
