Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

1386 m²

Step-by-step explanation:

Find the area of the park:

Area = πr²

Area = π(28)²  = 2464 m²

Find the area of the park and the road:

Area = πr²

Area = π(28 + 7)²  = 3850 m²

Find the area of the road:

Area = 3850 - 2464 = 1386 m²

Answer: 1386 m²
