A circular garden has a diameter of 4 meters, and a 25 cm wide path is to be constructed all around it. What is the approximate area of this path in square meters?

Explanation

To find the area of the path, subtract the area of the garden from the area of the larger circle formed by the garden plus the path. The radius of the garden is 2 m, and the path adds 0.25 m, making the outer radius 2.25 m. Area of the path = π(2.25²) - π(2²) = π(5.0625 - 4) = π(1.0625) ≈ 3.34 square meters.
