Answer:
![178.98\ \text{m}^2](https://tex.z-dn.net/?f=178.98%5C%20%5Ctext%7Bm%7D%5E2)
Step-by-step explanation:
d = Diameter of flower bed = 16 m
Thickness of sidewalk = 3 m
r = Radius of flower bed = ![\dfrac{d}{2}=\dfrac{16}{2}=8\ \text{m}](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7B2%7D%3D%5Cdfrac%7B16%7D%7B2%7D%3D8%5C%20%5Ctext%7Bm%7D)
R = Radius of flower bed with sidewalk = ![8+3=11\ \text{m}](https://tex.z-dn.net/?f=8%2B3%3D11%5C%20%5Ctext%7Bm%7D)
The required area is given by
![A=\pi(R^2-r^2)\\\Rightarrow A=3.14\times (11^2-8^2)\\\Rightarrow A=178.98\ \text{m}^2](https://tex.z-dn.net/?f=A%3D%5Cpi%28R%5E2-r%5E2%29%5C%5C%5CRightarrow%20A%3D3.14%5Ctimes%20%2811%5E2-8%5E2%29%5C%5C%5CRightarrow%20A%3D178.98%5C%20%5Ctext%7Bm%7D%5E2)
The radius of the sidewalk is
