The area of circle is 379.94 cm².
Step-by-step explanation:
Given,
Radius of circle = 11 centimeters
We have to calculate the area of circle.
We know that;
Area of circle = ![\pi r^2](https://tex.z-dn.net/?f=%5Cpi%20r%5E2)
Here;
π = 3.14 , r = 11
Area of circle = ![3.14*(11)^2](https://tex.z-dn.net/?f=3.14%2A%2811%29%5E2)
Area of circle = 3.14*121
Area of circle = 379.94 squared centimeters
The area of circle is 379.94 squared centimeters.

f(x) = 12 when x=2
Step-by-step explanation:
Given that
f(x) is inversely proportional to x
This is mathematical written as
f(x) ∝1/x
It can be written as:
![f(x) = \frac{k}{x}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7Bk%7D%7Bx%7D)
where k is the proportionality constant
So,
![8 = \frac{k}{3}\\8 * 3 = k\\k = 24](https://tex.z-dn.net/?f=8%20%3D%20%5Cfrac%7Bk%7D%7B3%7D%5C%5C8%20%2A%203%20%3D%20k%5C%5Ck%20%3D%2024)
Now the equation will be:
![f(x) = \frac{24}{x}\\Putting\ x=2\\f(x) = \frac{24}{2}\\f(x) = 12](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Cfrac%7B24%7D%7Bx%7D%5C%5CPutting%5C%20x%3D2%5C%5Cf%28x%29%20%3D%20%5Cfrac%7B24%7D%7B2%7D%5C%5Cf%28x%29%20%3D%2012)
Hence,
f(x) = 12 when x=2
