Answer:
16π ≈ 50.24 square feet
Explanation:
You want the area of an 8-foot circular window.
Area
The area of a circle can be found from ...
A = (π/4)d²
A = (π/4)·8² = 16π . . . . . square feet
If you use π = 3.14, the area is ...
(16 ft²)(3.14) = 50.24 ft²
The window's area is about 50.24 square feet.

Additional comment
If you use the "pi-button", you get a value of 50.27 ft². One will round to 50.2, and the other will round to 50.3. Both will round to 50 ft².
No pi value or rounding instructions are given here, so you need to choose the answer your grader expects.
