To find the area of a circle, you can use the formula:
\[
\text{Area} = \pi r^2
\]
where \( r \) is the radius. In this case, you mentioned "8 cm", which I will assume is the diameter. The radius \( r \) is half of the diameter:
\[
r = \frac{8 \text{ cm}}{2} = 4 \text{ cm}
\]
Now we can calculate the area:
\[
\text{Area} = \pi (4 \text{ cm})^2 = \pi \times 16 \text{ cm}^2 \approx 3.14159 \times 16 \text{ cm}^2 \approx 50.3 \text{ cm}^2
\]
Now let's check the options available:
- 254.5 sq cm
- 804.4 sq cm
- 25.1 sq cm
- 201.1 sq cm
Since the calculated area of \( 50.3 \text{ cm}^2 \) does not match any of the options, let's check if "8 cm" possibly refers to the side length of a square instead. The area of a square is calculated as:
\[
\text{Area} = \text{side}^2
\]
For a square with a side length of 8 cm:
\[
\text{Area} = (8 \text{ cm})^2 = 64 \text{ cm}^2
\]
Again, \( 64 \text{ cm}^2 \) does not match the options provided.
Since neither calculations fit the provided options and to clarify: if "8 cm" is indeed the side length of a different shape, please indicate which shape it is (circle, square, rectangle, etc.), and I will re-evaluate the calculation.
