Circular path 2m wide around park (radius 10m). Area of path?

Question

Accepted Answer

1. Outer radius = $10+2=12$ m.

2. Area of path = area of big circle − area of small circle = $\pi(12^2-10^2)$.

3. Compute: $12^2-10^2=144-100=44$, so area = $44\pi\approx44	imes3.1416=138.23$ m$^2$.

4. Closest option is **(b) 138.2 m²**.
