Area of a Path Around a Circular Park

A circular park has a radius of 12 meters. A path that is 3 meters wide is built around the park. What is the area of the path?

To find the area of the path, first calculate the area of the larger circle (the park plus the path) and then subtract the area of the park itself. Use the formula for the area of a circle, $$A = ext{π} r^2$$ where $r$ is the radius.
