To find the area of a circle, you can use the formula:
\[ \text{Area} = \pi r^2 \]
where \( \pi \) is approximately 3.14 and \( r \) is the radius.
Given:
- Radius \( r = 10 \) cm
- \( \pi \approx 3.14 \)
Now, substitute the values into the formula:
\[ \text{Area} = 3.14 \times (10)^2 \] \[ \text{Area} = 3.14 \times 100 \] \[ \text{Area} = 314 , \text{cm}^2 \]
Therefore, the best answer is:
D. 314 cm²
