To find the area of a circle, you can use the formula:
\[ \text{Area} = \pi r^2 \]
where \( r \) is the radius of the circle. Since the radius isn't provided in your question, I will demonstrate how to calculate the area based on various potential radii.
- For a radius of 5 cm:
\[ \text{Area} = 3.14 \times (5^2) = 3.14 \times 25 = 78.5 , \text{cm}^2 \]
- For a radius of 10 cm:
\[ \text{Area} = 3.14 \times (10^2) = 3.14 \times 100 = 314.0 , \text{cm}^2 \]
- For a radius of 2 cm:
\[ \text{Area} = 3.14 \times (2^2) = 3.14 \times 4 = 12.56 , \text{cm}^2 \]
- For a radius of 10 cm (to check if there is a second option):
\[ \text{Area} = 3.14 \times (10^2) = 3.14 \times 100 = 314.0 , \text{cm}^2 \]
From the options you provided, it seems most likely that your radius is either 5 cm or 10 cm. The areas corresponding to those are 78.5 cm² (Option C) or 314.0 cm² (Option D).
To answer your question based on common radii:
- If the radius is 5 cm, choose C (78.5 cm²).
- If the radius is 10 cm, choose D (314.0 cm²).
If you provide the radius, I can give you a precise answer!
