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
