To calculate the area of a circle, you can use the formula:
\[ A = \pi r^2 \]
Where:
- \( A \) is the area of the circle,
- \( \pi \) (approximately 3.14 or \(\frac{22}{7}\)) is a constant,
- \( r \) is the radius of the circle.
Step-by-Step Calculation
-
Identify the radius: First, you need to know the radius (\(r\)) of the circle. Let's assume, for this example, that the radius of the circle is 5 units.
-
Square the radius: Calculate \(r^2\). \[ r^2 = 5^2 = 25 \]
-
Multiply by \(\pi\): Now, substitute \(r^2\) into the area formula. \[ A = \pi \times 25 \]
-
Calculate the area: Using \( \pi \approx 3.14\) for calculation. \[ A \approx 3.14 \times 25 = 78.5 \]
Hence, the area of the circle is approximately \(78.5\) square units.
Final Answer
\[ A \approx 78.5 , \text{square units} \]
Make sure to replace the radius used in this example with the actual radius you have if it differs from 5 units. If you have a specific radius in mind, just follow the same steps using that value.
