To find the area of a circle, you can use the formula:
\[ \text{Area} = \pi r^2 \]
Where:
- \( \pi \) is approximately 3.14
- \( r \) is the radius of the circle
Given the radius \( r = 10 \) cm, we can calculate the area as follows:
\[ \text{Area} = 3.14 \times (10 , \text{cm})^2 \] \[ \text{Area} = 3.14 \times 100 , \text{cm}^2 \] \[ \text{Area} = 314 , \text{cm}^2 \]
The area of the circle is \( 314 , \text{cm}^2 \).
Therefore, the correct answer is D. 314 cm².
