Area of Walkway Around Circular Garden

A circular garden has a diameter of 18 feet. The garden is surrounded by a walkway that is 2 feet wide all around. To find the area of the walkway, first determine the area of the circular garden and then the area of the larger circle formed by the outer edge of the walkway.

Use the formula for the area of a circle, given by:

$$A = ext{pi} imes r^2$$
