Given that the radius r of a circle is written as a function of the area A with the following equation:
![r=\sqrt[]{\frac{A}{\pi}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B%5D%7B%5Cfrac%7BA%7D%7B%5Cpi%7D%7D)
The domain of the above function is the area A of the circle.
This is because, in this context, the area is an independent and unique variable.
A is the input value.
Answer:
36 cm^2.
Step-by-step explanation:
The area is half the product of the lengths of its diagonals.
(PA)(LY) = (12cm)(6cm)
= 72 cm
72cm ÷2= 36 cm^2
Therefore the area is 36 cm^2
There you go, the answer is circled. The rest is the work that goes to it.
