17. Kris used \( 23 \pi \) feet of fencing to enclose his circular garden. How wide is the garden at its widest?

Step 1 ：\text{Let }r\text{ be the radius of the circular garden}

Step 2 ：\text{The circumference of the circle is: } C = 2\pi r

Step 3 ：2\pi r = 23\pi

Step 4 ：\text{Divide both sides by }2\pi\text{: } r = \frac{23}{2}

Step 5 ：d = 2r

Step 6 ：d = 2 \times \frac{23}{2}
