the area of a circular tabletop with radius \( r \) the radius of a circular tabletop with circumference \( C \) the radius of a circular tabletop with circumference \( C \) tabletop with area \( A \)

To calculate the area of a circular tabletop, you can use the formula \( A = \pi r^2 \), where \( r \) is the radius. So, if your tabletop has a radius of 2 feet, the area would be quite the party space, amounting to about 12.57 square feet—enough to fit some appetizers and drinks! If you have the circumference \( C \) of your circular tabletop, you can find the radius using the formula \( r = \frac{C}{2\pi} \). For instance, if the circumference is 31.4 inches, then the radius would be 5 inches. That’s a manageable size for a cozy game night or craft session!
