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.
Given:
- Radius (\( r \)) = 15 inches
- \( \pi \) ≈ 3.14
Now, plug the values into the formula:
\[
\text{Area} = 3.14 \times (15)^2
\]
\[
\text{Area} = 3.14 \times 225
\]
\[
\text{Area} = 706.5 \, \text{in}^2
\]
Therefore, the area of the circle is **706.5 in²**.
\[ \text{Area} = \pi r^2 \]
