7.83m2
32.29m2
50.29m2
82.50m2
Correct answer is D
Area of path = Area of (pond+path) - Area of pond
The area of the pond with the path: The radius = (4 + 2.5)m = 6.5m
Area = π×r2 = 227×6.52≊
Area of the pond = \frac{22}{7} \times 4^{2} \approxeq 50.29m^{2}
Area of the path = (132.79 - 50.29)m^{2} = 82.50m^{2}\)
