To find the area of a circle, you can use the formula \( A = \pi r^2 \). Plugging in the radius of 20.4 inches, we get: \[ A \approx 3.14 \times (20.4)^2 \] \[ A \approx 3.14 \times 416.16 \] \[ A \approx 1308.78 \] So, the area of the circle is approximately 1308.78 square inches when rounded to the nearest hundredth. Calculating the area of a circle is a great skill in practical scenarios! For instance, if you’re planning a garden that’s circular, knowing the area can help in determining the amount of mulch or soil needed. Just measure the radius, plug into the area formula, and voilà—you have the land you’re working with. When working with formulas like this, it’s common to forget to square the radius! Always double-check your calculations for accuracy. Another common mistake is misplacing the decimal point in the final answer, so pay attention to detail while doing math, especially with larger numbers!
