4)) The radius of a circle is 3 centimeters. What is the circle's area? 4)) Use \( \pi \approx 3.14 \) and round your answer to the nearest hundredth. square centimeters

To find the area of a circle, you can use the formula \( A = \pi r^2 \). With a radius (\( r \)) of 3 centimeters, you'd calculate the area as \( A = 3.14 \times (3^2) \), which simplifies to \( A = 3.14 \times 9 \). This gives us an area of approximately 28.26 square centimeters when rounded to the nearest hundredth. Circles are everywhere in our daily lives, from wheels to pizza! Understanding how to calculate their area can help you with practical tasks like figuring out how much paint you'll need for a circular surface, or how much grass seed to buy for a circular garden plot. Knowing the area makes planning a piece of cake!
