F(x) basically is a 0-input function from what I can see. The output is always 2, so no matter what x is, the result will be 2. Therefore f(x + 2) = 2.
Answer:
216![\pi](https://tex.z-dn.net/?f=%5Cpi)
Step-by-step explanation:
Given the figure.
And the perimeter in the ratio 4: 2: 1.
Perimeter of smallest circle = ![8\pi](https://tex.z-dn.net/?f=8%5Cpi)
To find:
Area of shaded region.
Solution:
To find the area, we need to have radius first.
And radius can be calculated by the given perimeter.
Formula for Perimeter is given as:
Perimeter = ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
![8\pi = 2\pi r\\\Rightarrow r = 4\ cm](https://tex.z-dn.net/?f=8%5Cpi%20%3D%202%5Cpi%20r%5C%5C%5CRightarrow%20r%20%3D%204%5C%20cm)
Radius of smallest circle = 4 cm
Ratio of perimeter is equal to the ratio of the radii.
Radius of 2nd smallest circle by the given ratio = 8 cm
Radius of largest circle = 16 cm
Area of a circle is given the formula:
![A = \pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cpi%20r%5E2)
Area of the smallest circle = ![\pi 4^2 = 16\pi\ cm^2](https://tex.z-dn.net/?f=%5Cpi%204%5E2%20%3D%2016%5Cpi%5C%20cm%5E2)
Area of the 2nd smallest circle = ![\pi 8^2 = 64\pi\ cm^2](https://tex.z-dn.net/?f=%5Cpi%208%5E2%20%3D%2064%5Cpi%5C%20cm%5E2)
Area of the largest circle = ![\pi 16^2 = 256\pi\ cm^2](https://tex.z-dn.net/?f=%5Cpi%2016%5E2%20%3D%20256%5Cpi%5C%20cm%5E2)
Area of the shaded region = Area of largest circle + 2
Area of 2nd smallest circle + 3
Area of smallest circle - 2
Area of smallest circle - 3
Area of 2nd smallest circle
Area of the shaded region = Area of largest circle - Area of 2nd smallest circle + Area of smallest circle = ![256\pi - 64\pi +16\pi = 216\pi](https://tex.z-dn.net/?f=256%5Cpi%20-%2064%5Cpi%20%2B16%5Cpi%20%3D%20216%5Cpi)
