Answer:

x = 15.4

Step-by-step explanation:

Because this is a right triangle, you can use the pythagorean theorem to find the length of the hypotenuse. the theorem is a^2 + b^2 = c^2

so

9^2 + 12.5^2 = c^2

solving this will give you 15.4

The domain of the function is \[A \ge0\] If A is negative we get an imaginary number for the radius. This makes sense because the area of a circle cannot be negative.
