Question
A circular garden has a radius of 14 m. A path of width
2 m is constructed all around it outside. Find the approximate area of the path. (Use π = 22/7)Solution
Inner radius r = 14 m Outer radius R = 14 + 2 = 16 m Area of path = π(R² − r²) = (22/7)(16² − 14²) = (22/7)(256 − 196) = (22/7) × 60 = 22 × (60/7) = 1,320/7 ≈ 188.57 m²
