Answer:
16
Step-by-step explanation:
The formula for the area of a circle is
![\pi {r}^{2}](https://tex.z-dn.net/?f=%5Cpi%20%7Br%7D%5E%7B2%7D%20)
so you simply plug your value for radius into the equation!
![\pi {(14)}^{2}](https://tex.z-dn.net/?f=%5Cpi%20%7B%2814%29%7D%5E%7B2%7D%20)
Square 14
![196\pi](https://tex.z-dn.net/?f=196%5Cpi)
And Multiply by pi!
615.75 cm^2 approximately!
I hope this helps!

Answer:
f^-1(x) = 4x^2 -3 . . . . x ≤ 0
Step-by-step explanation:
Interchange x and y, then solve for y.
x = -1/2√(y+3)
-2x = √(y +3)
4x^2 = y +3
4x^2 -3 = y
Note that the range of the function f(x) is f(x) ≤ 0, so this will be the domain of the inverse function. Then the inverse function is ...
f^-1(x) = 4x^2 -3 . . . . for x ≤ 0
___
The attached graph shows this inverse function is a reflection of the function across the line y=x, as it should be.
