A circular garden has a radius of 18 m. A 2.5 m wide pathway is constructed around it. What is the approximate area of the pathway?

Question

Accepted Answer

1. Outer radius: $R = 18 + 2.5 = 20.5$ m.

2. Area of the path = $\pi(R^2 - r^2) = \pi(20.5^2 - 18^2) = \pi(420.25 - 324) = 96.25\pi$.

3. Approximate value: $96.25\pi \approx 96.25	imes 3.1416 \approx 302.53\ 	ext{m}^2$.

4. The closest option is **(b) 302 m²**.
