To find the area of a circle, you can use the formula \( A = \pi r^2 \), where \( r \) is the radius. If your circle has a radius (for example, let's say the radius is 5), then you would calculate \( A = \pi (5^2) = \pi \times 25 \). If we use 3.14 for \( \pi \), the area becomes \( A \approx 3.14 \times 25 = 78.5 \) square units. So, the approximate area rounded to the nearest hundredth is 78.50 square units. Now, if you’re looking for a real-world application, circles pop up everywhere—from pizzas to basketball courts! Understanding how to calculate the area can help you determine how much topping can fit on a pizza or the flooring you might need for a circular room. Knowing the area helps with planning and making informed decisions!
