The area of a circle is calculated using the formula A = 𝜋r^2, where A is the area and r is the radius.
Plugging in the given values, we have A = 3.14 * 18^2:
A = 3.14 * 324
A ≈ 1015.44
Therefore, the placemat's area is approximately 1015.44 square centimeters.
Michael uses a circular placemat with a radius of 18 centimeters. What is the placemat's area?
Use 3.14 for 𝜋. If necessary, round your answer to the nearest hundredth.
