To find the area of a circle, you can use the formula:
\[ A = \pi r^2 \]
where \( r \) is the radius of the circle. The radius is half of the diameter.
Given that the diameter is 8 inches, the radius \( r \) is:
\[ r = \frac{8}{2} = 4 \text{ inches} \]
Now plug the radius into the formula for the area:
\[ A = \pi (4)^2 = \pi \times 16 \]
Using the approximate value of \( \pi \approx 3.14 \):
\[ A \approx 3.14 \times 16 \approx 50.24 \text{ square inches} \]
Thus, the area of the circle is approximately \( 50 \text{ in}^2 \).
So, the correct response is:
50 in. squared
