![**Problem 6: Calculating the Area within a Circle but outside an Inscribed Regular Hexagon**
Given a regular hexagon with side lengths of 16 cm, inscribed in a circle, the task is to determine the area enclosed by the circle but lying outside the hexagon. In order to solve this problem, follow these steps:
1. **Calculate the Radius of the Circumscribed Circle:**
- For a regular hexagon inscribed in a circle, the radius of the circle is equal to the length of the side of the hexagon. Therefore, the radius \(r\) of the circle is 16 cm.
2. **Find the Area of the Circle:**
- The formula for the area of a circle is \(A = \pi r^2\).
- Substitute the value of \(r\) to get the area:
\[
A = \pi \times (16)^2 = 256\pi \text{ cm}^2
\]
3. **Calculate the Area of the Regular Hexagon:**
- The formula for the area of a regular hexagon with side length \(s\) is \(\frac{3\sqrt{3}}{2} s^2\).
- Substitute the value of \(s\) to find the area:
\[
A_{\text{hexagon}} = \frac{3\sqrt{3}}{2} \times (16)^2 = 384\sqrt{3} \text{ cm}^2
\]
4. **Determine the Area between the Circle and the Hexagon:**
- Subtract the area of the hexagon from the area of the circle:
\[
A_{\text{region}} = 256\pi - 384\sqrt{3} \text{ cm}^2
\]
This final value represents the area inside the circle but outside the hexagon.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F56343518-6573-4718-8606-b00cef1fba0c%2Ff4d2eb1c-666a-464c-b9f5-956aa19dd4f6%2Fqp8wg48_processed.png&w=3840&q=75)
