Answer:
The area is approximately 453 ft²
Step-by-step explanation:
Area of a circle = 
If
= 22/7, and r = 12 ft
Area = (22/7)×12²
= 3.143*144
= 452.592 ft²
≈ 453 ft²
For this case we must solve the following system of equations:

We clear x of both equations:

We match:

We find the value of "x":

Thus, the solution of the system is:
