Answer:
Find the area of the park:
Area = πr²
Area = π(15)² = 225π m²
Find the radius of the park and road:
Radius = 15 + 10 = 25 m
Find the area of the park and road:
Area = πr²
Area = π(25)² = 625π m²
Find the area of the road:
Area = 625π - 225π = 400π = 1257.14 m²
Answer: The area of the road is 1257.14 m²
